Texture holding ambient occlusion, roughness, and metallic.
TextureParam TEXTURE_MAX = 18
Represents the size of the TextureParam enum.
enum TextureFilter:
TextureFilter TEXTURE_FILTER_NEAREST = 0
The texture filter reads from the nearest pixel only. The simplest and fastest method of filtering, but the texture will look pixelized.
TextureFilter TEXTURE_FILTER_LINEAR = 1
The texture filter blends between the nearest 4 pixels. Use this when you want to avoid a pixelated style, but do not want mipmaps.
TextureFilter TEXTURE_FILTER_NEAREST_WITH_MIPMAPS = 2
The texture filter reads from the nearest pixel in the nearest mipmap. The fastest way to read from textures with mipmaps.
TextureFilter TEXTURE_FILTER_LINEAR_WITH_MIPMAPS = 3
The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps. Use this for most cases as mipmaps are important to smooth out pixels that are far from the camera.
TextureFilter TEXTURE_FILTER_NEAREST_WITH_MIPMAPS_ANISOTROPIC = 4
The texture filter reads from the nearest pixel, but selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera. The anisotropic filtering level can be changed by adjusting ProjectSettings.rendering/textures/default_filters/anisotropic_filtering_level.
TextureFilter TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC = 5
The texture filter blends between the nearest 4 pixels and selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera. This is the slowest of the filtering options, but results in the highest quality texturing. The anisotropic filtering level can be changed by adjusting ProjectSettings.rendering/textures/default_filters/anisotropic_filtering_level.
TextureFilter TEXTURE_FILTER_MAX = 6
Represents the size of the TextureFilter enum.

The material will use the texture’s alpha values for transparency. This is the slowest to render, and disables shadow casting.
Transparency TRANSPARENCY_ALPHA_SCISSOR = 2
The material will cut off all values below a threshold, the rest will remain opaque. The opaque portions will be rendered in the depth prepass. This is faster to render than alpha blending, but slower than opaque rendering. This also supports casting shadows.
Transparency TRANSPARENCY_ALPHA_HASH = 3
The material will cut off all values below a spatially-deterministic threshold, the rest will remain opaque. This is faster to render than alpha blending, but slower than opaque rendering. This also supports casting shadows. Alpha hashing is suited for hair rendering.
Transparency TRANSPARENCY_ALPHA_DEPTH_PRE_PASS = 4
The material will use the texture’s alpha value for transparency, but will discard fragments with an alpha of less than 0.99 during the depth prepass and fragments with an alpha less than 0.1 during the shadow pass. This also supports casting shadows.
Transparency TRANSPARENCY_MAX = 5
Represents the size of the Transparency enum.
enum ShadingMode:
ShadingMode SHADING_MODE_UNSHADED = 0

The object will be shaded per pixel. Useful for realistic shading effects.
ShadingMode SHADING_MODE_PER_VERTEX = 2
The object will be shaded per vertex. Useful when you want cheaper shaders and do not care about visual quality. Not implemented yet (this mode will act like SHADING_MODE_PER_PIXEL).

AlphaAntiAliasing ALPHA_ANTIALIASING_ALPHA_TO_COVERAGE_AND_TO_ONE = 2
Enables AlphaToCoverage and forces all non-zero alpha values to 1. Alpha values in the material are passed to the AntiAliasing sample mask.
enum DepthDrawMode:
DepthDrawMode DEPTH_DRAW_OPAQUE_ONLY = 0
Default depth draw mode. Depth is drawn only for opaque objects during the opaque prepass (if any) and during the opaque pass.
DepthDrawMode DEPTH_DRAW_ALWAYS = 1
Objects will write to depth during the opaque and the transparent passes. Transparent objects that are close to the camera may obscure other transparent objects behind them.
Note: This does not influence whether transparent objects are included in the depth prepass or not. For that, see Transparency.
DepthDrawMode DEPTH_DRAW_DISABLED = 2
Objects will not write their depth to the depth buffer, even during the depth prepass (if enabled).
enum CullMode:
CullMode CULL_BACK = 0
Default cull mode. The back of the object is culled when not visible. Back face triangles will be culled when facing the camera. This results in only the front side of triangles being drawn. For closed-surface meshes, this means that only the exterior of the mesh will be visible.
CullMode CULL_FRONT = 1
Front face triangles will be culled when facing the camera. This results in only the back side of triangles being drawn. For closed-surface meshes, this means that the interior of the mesh will be drawn instead of the exterior.
CullMode CULL_DISABLED = 2
No face culling is performed; both the front face and back face will be visible.
enum Flags:
Flags FLAG_DISABLE_DEPTH_TEST = 0
Disables the depth test, so this object is drawn on top of all others drawn before it. This puts the object in the transparent draw pass where it is sorted based on distance to camera. Objects drawn after it in the draw order may cover it. This also disables writing to depth.
Flags FLAG_ALBEDO_FROM_VERTEX_COLOR = 1
Set ALBEDO to the per-vertex color specified in the mesh.
Flags FLAG_SRGB_VERTEX_COLOR = 2
Vertex colors are considered to be stored in sRGB color space and are converted to linear color space during rendering. See also vertex_color_is_srgb.
Note: Only effective when using the Forward+ and Mobile rendering methods.
Flags FLAG_USE_POINT_SIZE = 3
Uses point size to alter the size of primitive points. Also changes the albedo texture lookup to use POINT_COORD instead of UV.
Flags FLAG_FIXED_SIZE = 4
Object is scaled by depth so that it always appears the same size on screen.
Flags FLAG_BILLBOARD_KEEP_SCALE = 5
Shader will keep the scale set for the mesh. Otherwise the scale is lost when billboarding. Only applies when billboard_mode is BILLBOARD_ENABLED.
Flags FLAG_UV1_USE_TRIPLANAR = 6
Use triplanar texture lookup for all texture lookups that would normally use UV.
Flags FLAG_UV2_USE_TRIPLANAR = 7
Use triplanar texture lookup for all texture lookups that would normally use UV2.

Flags FLAG_EMISSION_ON_UV2 = 11
Use UV2 coordinates to look up from the emission_texture.
Flags FLAG_ALBEDO_TEXTURE_FORCE_SRGB = 12

Flags FLAG_DONT_RECEIVE_SHADOWS = 13
Disables receiving shadows from other objects.
Flags FLAG_DISABLE_AMBIENT_LIGHT = 14
Disables receiving ambient light.
Flags FLAG_USE_SHADOW_TO_OPACITY = 15
Enables the shadow to opacity feature.
Flags FLAG_USE_TEXTURE_REPEAT = 16
Enables the texture to repeat when UV coordinates are outside the 0-1 range. If using one of the linear filtering modes, this can result in artifacts at the edges of a texture when the sampler filters across the edges of the texture.
Flags FLAG_INVERT_HEIGHTMAP = 17
Invert values read from a depth texture to convert them to height values (heightmap).
Flags FLAG_SUBSURFACE_MODE_SKIN = 18
Enables the skin mode for subsurface scattering which is used to improve the look of subsurface scattering when used for human skin.
Flags FLAG_PARTICLE_TRAILS_MODE = 19
Enables parts of the shader required for GPUParticles3D trails to function. This also requires using a mesh with appropriate skinning, such as RibbonTrailMesh or TubeTrailMesh. Enabling this feature outside of materials used in GPUParticles3D meshes will break material rendering.
Flags FLAG_ALBEDO_TEXTURE_MSDF = 20
Enables multichannel signed distance field rendering shader.
Flags FLAG_DISABLE_FOG = 21
Disables receiving depth-based or volumetric fog.
Flags FLAG_MAX = 22
Represents the size of the Flags enum.
enum DiffuseMode:
DiffuseMode DIFFUSE_BURLEY = 0

Used for particle systems when assigned to GPUParticles3D and CPUParticles3D nodes (flipbook animation). Enables particles_anim_* properties.
The ParticleProcessMaterial.anim_speed_min or CPUParticles3D.anim_speed_min should also be set to a value bigger than zero for the animation to play.

Used to read from the red channel of a texture.
TextureChannel TEXTURE_CHANNEL_GREEN = 1
Used to read from the green channel of a texture.

Smoothly fades the object out based on each pixel’s distance from the camera using a dithering approach. Dithering discards pixels based on a set pattern to smoothly fade without enabling transparency. On certain hardware, this can be faster than DISTANCE_FADE_PIXEL_ALPHA.
DistanceFadeMode DISTANCE_FADE_OBJECT_DITHER = 3
Smoothly fades the object out based on the object’s distance from the camera using a dithering approach. Dithering discards pixels based on a set pattern to smoothly fade without enabling transparency. On certain hardware, this can be faster than DISTANCE_FADE_PIXEL_ALPHA and DISTANCE_FADE_PIXEL_DITHER.
Property Descriptions
Color albedo_color = Color(1, 1, 1, 1)
The material’s base color.
Note: If detail_enabled is true and a detail_albedo texture is specified, albedo_color will not modulate the detail texture. This can be used to color partial areas of a material by not specifying an albedo texture and using a transparent detail_albedo texture instead.
Texture2D albedo_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture to multiply by albedo_color. Used for basic texturing of objects.
If the texture appears unexpectedly too dark or too bright, check albedo_texture_force_srgb.
bool albedo_texture_force_srgb = false
If true, forces a conversion of the albedo_texture from sRGB color space to linear color space. See also vertex_color_is_srgb.
This should only be enabled when needed (typically when using a ViewportTexture as albedo_texture). If albedo_texture_force_srgb is true when it shouldn’t be, the texture will appear to be too dark. If albedo_texture_force_srgb is false when it shouldn’t be, the texture will appear to be too bright.
bool albedo_texture_msdf = false
Enables multichannel signed distance field rendering shader. Use msdf_pixel_range and msdf_outline_size to configure MSDF parameters.
float alpha_antialiasing_edge
Threshold at which antialiasing will be applied on the alpha channel.
AlphaAntiAliasing alpha_antialiasing_mode
void set_alpha_antialiasing ( AlphaAntiAliasing value )
AlphaAntiAliasing get_alpha_antialiasing ( )
The type of alpha antialiasing to apply. See AlphaAntiAliasing.
float alpha_hash_scale
The hashing scale for Alpha Hash. Recommended values between 0 and 2.
float alpha_scissor_threshold
Threshold at which the alpha scissor will discard values. Higher values will result in more pixels being discarded. If the material becomes too opaque at a distance, try increasing alpha_scissor_threshold. If the material disappears at a distance, try decreasing alpha_scissor_threshold.
float anisotropy = 0.0
The strength of the anisotropy effect. This is multiplied by anisotropy_flowmap‘s alpha channel if a texture is defined there and the texture contains an alpha channel.
bool anisotropy_enabled = false
If true, anisotropy is enabled. Anisotropy changes the shape of the specular blob and aligns it to tangent space. This is useful for brushed aluminium and hair reflections.
Note: Mesh tangents are needed for anisotropy to work. If the mesh does not contain tangents, the anisotropy effect will appear broken.
Note: Material anisotropy should not to be confused with anisotropic texture filtering, which can be enabled by setting texture_filter to TEXTURE_FILTER_LINEAR_WITH_MIPMAPS_ANISOTROPIC.
Texture2D anisotropy_flowmap
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that offsets the tangent map for anisotropy calculations and optionally controls the anisotropy effect (if an alpha channel is present). The flowmap texture is expected to be a derivative map, with the red channel representing distortion on the X axis and green channel representing distortion on the Y axis. Values below 0.5 will result in negative distortion, whereas values above 0.5 will result in positive distortion.
If present, the texture’s alpha channel will be used to multiply the strength of the anisotropy effect. Fully opaque pixels will keep the anisotropy effect’s original strength while fully transparent pixels will disable the anisotropy effect entirely. The flowmap texture’s blue channel is ignored.
bool ao_enabled = false
If true, ambient occlusion is enabled. Ambient occlusion darkens areas based on the ao_texture.
float ao_light_affect = 0.0
Amount that ambient occlusion affects lighting from lights. If 0, ambient occlusion only affects ambient light. If 1, ambient occlusion affects lights just as much as it affects ambient light. This can be used to impact the strength of the ambient occlusion effect, but typically looks unrealistic.
bool ao_on_uv2 = false
If true, use UV2 coordinates to look up from the ao_texture.
Texture2D ao_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that defines the amount of ambient occlusion for a given point on the object.
TextureChannel ao_texture_channel = 0
void set_ao_texture_channel ( TextureChannel value )
TextureChannel get_ao_texture_channel ( )
Specifies the channel of the ao_texture in which the ambient occlusion information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.
Color backlight = Color(0, 0, 0, 1)
The color used by the backlight effect. Represents the light passing through an object.
bool backlight_enabled = false
If true, the backlight effect is enabled. See also subsurf_scatter_transmittance_enabled.
Texture2D backlight_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to control the backlight effect per-pixel. Added to backlight.
bool billboard_keep_scale = false
If true, the shader will keep the scale set for the mesh. Otherwise, the scale is lost when billboarding. Only applies when billboard_mode is not BILLBOARD_DISABLED.
BillboardMode billboard_mode = 0
void set_billboard_mode ( BillboardMode value )
BillboardMode get_billboard_mode ( )
Controls how the object faces the camera. See BillboardMode.
Note: Billboard mode is not suitable for VR because the left-right vector of the camera is not horizontal when the screen is attached to your head instead of on the table. See GitHub issue #41567 for details.
BlendMode blend_mode = 0
The material’s blend mode.
Note: Values other than Mix force the object into the transparent pipeline. See BlendMode.
float clearcoat = 1.0
Sets the strength of the clearcoat effect. Setting to 0 looks the same as disabling the clearcoat effect.
bool clearcoat_enabled = false
If true, clearcoat rendering is enabled. Adds a secondary transparent pass to the lighting calculation resulting in an added specular blob. This makes materials appear as if they have a clear layer on them that can be either glossy or rough.
Note: Clearcoat rendering is not visible if the material’s shading_mode is SHADING_MODE_UNSHADED.
float clearcoat_roughness = 0.5
Sets the roughness of the clearcoat pass. A higher value results in a rougher clearcoat while a lower value results in a smoother clearcoat.
Texture2D clearcoat_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that defines the strength of the clearcoat effect and the glossiness of the clearcoat. Strength is specified in the red channel while glossiness is specified in the green channel.
CullMode cull_mode = 0
Determines which side of the triangle to cull depending on whether the triangle faces towards or away from the camera. See CullMode.
DepthDrawMode depth_draw_mode = 0
void set_depth_draw_mode ( DepthDrawMode value )
DepthDrawMode get_depth_draw_mode ( )
Determines when depth rendering takes place. See DepthDrawMode. See also transparency.
Texture2D detail_albedo
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that specifies the color of the detail overlay. detail_albedo‘s alpha channel is used as a mask, even when the material is opaque. To use a dedicated texture as a mask, see detail_mask.
Note: detail_albedo is not modulated by albedo_color.
BlendMode detail_blend_mode = 0
Specifies how the detail_albedo should blend with the current ALBEDO. See BlendMode for options.
bool detail_enabled = false
If true, enables the detail overlay. Detail is a second texture that gets mixed over the surface of the object based on detail_mask and detail_albedo‘s alpha channel. This can be used to add variation to objects, or to blend between two different albedo/normal textures.
Texture2D detail_mask
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to specify how the detail textures get blended with the base textures. detail_mask can be used together with detail_albedo‘s alpha channel (if any).
Texture2D detail_normal
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that specifies the per-pixel normal of the detail overlay. The detail_normal texture only uses the red and green channels; the blue and alpha channels are ignored. The normal read from detail_normal is oriented around the surface normal provided by the Mesh.
Note: Godot expects the normal map to use X+, Y+, and Z+ coordinates. See this page for a comparison of normal map coordinates expected by popular engines.
DetailUV detail_uv_layer = 0
Specifies whether to use UV or UV2 for the detail layer. See DetailUV for options.
DiffuseMode diffuse_mode = 0
void set_diffuse_mode ( DiffuseMode value )
DiffuseMode get_diffuse_mode ( )
The algorithm used for diffuse light scattering. See DiffuseMode.
bool disable_ambient_light = false
If true, the object receives no ambient light.
bool disable_fog = false
If true, the object will not be affected by fog (neither volumetric nor depth fog). This is useful for unshaded or transparent materials (e.g. particles), which without this setting will be affected even if fully transparent.
bool disable_receive_shadows = false
If true, the object receives no shadow that would otherwise be cast onto it.
float distance_fade_max_distance = 10.0
Distance at which the object appears fully opaque.
Note: If distance_fade_max_distance is less than distance_fade_min_distance, the behavior will be reversed. The object will start to fade away at distance_fade_max_distance and will fully disappear once it reaches distance_fade_min_distance.
float distance_fade_min_distance = 0.0
Distance at which the object starts to become visible. If the object is less than this distance away, it will be invisible.
Note: If distance_fade_min_distance is greater than distance_fade_max_distance, the behavior will be reversed. The object will start to fade away at distance_fade_max_distance and will fully disappear once it reaches distance_fade_min_distance.
DistanceFadeMode distance_fade_mode = 0
void set_distance_fade ( DistanceFadeMode value )
DistanceFadeMode get_distance_fade ( )
Specifies which type of fade to use. Can be any of the DistanceFadeModes.
Color emission = Color(0, 0, 0, 1)
The emitted light’s color. See emission_enabled.
bool emission_enabled = false
If true, the body emits light. Emitting light makes the object appear brighter. The object can also cast light on other objects if a VoxelGI, SDFGI, or LightmapGI is used and this object is used in baked lighting.
float emission_energy_multiplier = 1.0
Multiplier for emitted light. See emission_enabled.
float emission_intensity
Luminance of emitted light, measured in nits (candela per square meter). Only available when ProjectSettings.rendering/lights_and_shadows/use_physical_light_units is enabled. The default is roughly equivalent to an indoor lightbulb.
bool emission_on_uv2 = false
Use UV2 to read from the emission_texture.
EmissionOperator emission_operator = 0
void set_emission_operator ( EmissionOperator value )
EmissionOperator get_emission_operator ( )
Sets how emission interacts with emission_texture. Can either add or multiply. See EmissionOperator for options.
Texture2D emission_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that specifies how much surface emits light at a given point.
bool fixed_size = false
If true, the object is rendered at the same size regardless of distance.
bool grow = false
If true, enables the vertex grow setting. This can be used to create mesh-based outlines using a second material pass and its cull_mode set to CULL_FRONT. See also grow_amount.
Note: Vertex growth cannot create new vertices, which means that visible gaps may occur in sharp corners. This can be alleviated by designing the mesh to use smooth normals exclusively using face weighted normals in the 3D authoring software. In this case, grow will be able to join every outline together, just like in the original mesh.
float grow_amount = 0.0
Grows object vertices in the direction of their normals. Only effective if grow is true.
bool heightmap_deep_parallax = false
If true, uses parallax occlusion mapping to represent depth in the material instead of simple offset mapping (see heightmap_enabled). This results in a more convincing depth effect, but is much more expensive on the GPU. Only enable this on materials where it makes a significant visual difference.
bool heightmap_enabled = false
If true, height mapping is enabled (also called “parallax mapping” or “depth mapping”). See also normal_enabled. Height mapping is a demanding feature on the GPU, so it should only be used on materials where it makes a significant visual difference.
Note: Height mapping is not supported if triplanar mapping is used on the same material. The value of heightmap_enabled will be ignored if uv1_triplanar is enabled.
bool heightmap_flip_binormal = false
void set_heightmap_deep_parallax_flip_binormal ( bool value )
bool get_heightmap_deep_parallax_flip_binormal ( )
If true, flips the mesh’s binormal vectors when interpreting the height map. If the heightmap effect looks strange when the camera moves (even with a reasonable heightmap_scale), try setting this to true.
bool heightmap_flip_tangent = false
void set_heightmap_deep_parallax_flip_tangent ( bool value )
bool get_heightmap_deep_parallax_flip_tangent ( )
If true, flips the mesh’s tangent vectors when interpreting the height map. If the heightmap effect looks strange when the camera moves (even with a reasonable heightmap_scale), try setting this to true.
bool heightmap_flip_texture = false
If true, interprets the height map texture as a depth map, with brighter values appearing to be “lower” in altitude compared to darker values.
This can be enabled for compatibility with some materials authored for Godot 3.x. This is not necessary if the Invert import option was used to invert the depth map in Godot 3.x, in which case heightmap_flip_texture should remain false.
int heightmap_max_layers
void set_heightmap_deep_parallax_max_layers ( int value )
int get_heightmap_deep_parallax_max_layers ( )
The number of layers to use for parallax occlusion mapping when the camera is up close to the material. Higher values result in a more convincing depth effect, especially in materials that have steep height changes. Higher values have a significant cost on the GPU, so it should only be increased on materials where it makes a significant visual difference.
Note: Only effective if heightmap_deep_parallax is true.
int heightmap_min_layers
void set_heightmap_deep_parallax_min_layers ( int value )
int get_heightmap_deep_parallax_min_layers ( )
The number of layers to use for parallax occlusion mapping when the camera is far away from the material. Higher values result in a more convincing depth effect, especially in materials that have steep height changes. Higher values have a significant cost on the GPU, so it should only be increased on materials where it makes a significant visual difference.
Note: Only effective if heightmap_deep_parallax is true.
float heightmap_scale = 5.0
The heightmap scale to use for the parallax effect (see heightmap_enabled). The default value is tuned so that the highest point (value = 255) appears to be 5 cm higher than the lowest point (value = 0). Higher values result in a deeper appearance, but may result in artifacts appearing when looking at the material from oblique angles, especially when the camera moves. Negative values can be used to invert the parallax effect, but this is different from inverting the texture using heightmap_flip_texture as the material will also appear to be “closer” to the camera. In most cases, heightmap_scale should be kept to a positive value.
Note: If the height map effect looks strange regardless of this value, try adjusting heightmap_flip_binormal and heightmap_flip_tangent. See also heightmap_texture for recommendations on authoring heightmap textures, as the way the heightmap texture is authored affects how heightmap_scale behaves.
Texture2D heightmap_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
The texture to use as a height map. See also heightmap_enabled.
For best results, the texture should be normalized (with heightmap_scale reduced to compensate). In GIMP, this can be done using Colors > Auto > Equalize. If the texture only uses a small part of its available range, the parallax effect may look strange, especially when the camera moves.
Note: To reduce memory usage and improve loading times, you may be able to use a lower-resolution heightmap texture as most heightmaps are only comprised of low-frequency data.
float metallic = 0.0
A high value makes the material appear more like a metal. Non-metals use their albedo as the diffuse color and add diffuse to the specular reflection. With non-metals, the reflection appears on top of the albedo color. Metals use their albedo as a multiplier to the specular reflection and set the diffuse color to black resulting in a tinted reflection. Materials work better when fully metal or fully non-metal, values between 0 and 1 should only be used for blending between metal and non-metal sections. To alter the amount of reflection use roughness.
float metallic_specular = 0.5
Adjusts the strength of specular reflections. Specular reflections are composed of scene reflections and the specular lobe which is the bright spot that is reflected from light sources. When set to 0.0, no specular reflections will be visible. This differs from the SPECULAR_DISABLED SpecularMode as SPECULAR_DISABLED only applies to the specular lobe from the light source.
Note: Unlike metallic, this is not energy-conserving, so it should be left at 0.5 in most cases. See also roughness.
Texture2D metallic_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to specify metallic for an object. This is multiplied by metallic.
TextureChannel metallic_texture_channel = 0
void set_metallic_texture_channel ( TextureChannel value )
TextureChannel get_metallic_texture_channel ( )
Specifies the channel of the metallic_texture in which the metallic information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.
float msdf_outline_size = 0.0
The width of the shape outline.
float msdf_pixel_range = 4.0
The width of the range around the shape between the minimum and maximum representable signed distance.
bool no_depth_test = false
If true, depth testing is disabled and the object will be drawn in render order.
bool normal_enabled = false
If true, normal mapping is enabled. This has a slight performance cost, especially on mobile GPUs.
float normal_scale = 1.0
The strength of the normal map’s effect.
Texture2D normal_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to specify the normal at a given pixel. The normal_texture only uses the red and green channels; the blue and alpha channels are ignored. The normal read from normal_texture is oriented around the surface normal provided by the Mesh.
Note: The mesh must have both normals and tangents defined in its vertex data. Otherwise, the normal map won’t render correctly and will only appear to darken the whole surface. If creating geometry with SurfaceTool, you can use SurfaceTool.generate_normals and SurfaceTool.generate_tangents to automatically generate normals and tangents respectively.
Note: Godot expects the normal map to use X+, Y+, and Z+ coordinates. See this page for a comparison of normal map coordinates expected by popular engines.
Note: If detail_enabled is true, the detail_albedo texture is drawn below the normal_texture. To display a normal map above the detail_albedo texture, use detail_normal instead.
Texture2D orm_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
The Occlusion/Roughness/Metallic texture to use. This is a more efficient replacement of ao_texture, roughness_texture and metallic_texture in ORMMaterial3D. Ambient occlusion is stored in the red channel. Roughness map is stored in the green channel. Metallic map is stored in the blue channel. The alpha channel is ignored.
int particles_anim_h_frames
The number of horizontal frames in the particle sprite sheet. Only enabled when using BILLBOARD_PARTICLES. See billboard_mode.
bool particles_anim_loop
If true, particle animations are looped. Only enabled when using BILLBOARD_PARTICLES. See billboard_mode.
int particles_anim_v_frames
The number of vertical frames in the particle sprite sheet. Only enabled when using BILLBOARD_PARTICLES. See billboard_mode.
float point_size = 1.0
The point size in pixels. See use_point_size.
float proximity_fade_distance = 1.0
Distance over which the fade effect takes place. The larger the distance the longer it takes for an object to fade.
bool proximity_fade_enabled = false
If true, the proximity fade effect is enabled. The proximity fade effect fades out each pixel based on its distance to another object.
bool refraction_enabled = false
If true, the refraction effect is enabled. Distorts transparency based on light from behind the object.
float refraction_scale = 0.05
The strength of the refraction effect.
Texture2D refraction_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture that controls the strength of the refraction per-pixel. Multiplied by refraction_scale.
TextureChannel refraction_texture_channel = 0
void set_refraction_texture_channel ( TextureChannel value )
TextureChannel get_refraction_texture_channel ( )
Specifies the channel of the refraction_texture in which the refraction information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored refraction in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.
float rim = 1.0
Sets the strength of the rim lighting effect.
bool rim_enabled = false
If true, rim effect is enabled. Rim lighting increases the brightness at glancing angles on an object.
Note: Rim lighting is not visible if the material’s shading_mode is SHADING_MODE_UNSHADED.
Texture2D rim_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to set the strength of the rim lighting effect per-pixel. Multiplied by rim.
float rim_tint = 0.5
The amount of to blend light and albedo color when rendering rim effect. If 0 the light color is used, while 1 means albedo color is used. An intermediate value generally works best.
float roughness = 1.0
Surface reflection. A value of 0 represents a perfect mirror while a value of 1 completely blurs the reflection. See also metallic.
Texture2D roughness_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to control the roughness per-pixel. Multiplied by roughness.
TextureChannel roughness_texture_channel = 0
void set_roughness_texture_channel ( TextureChannel value )
TextureChannel get_roughness_texture_channel ( )
Specifies the channel of the roughness_texture in which the roughness information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.
ShadingMode shading_mode = 1
void set_shading_mode ( ShadingMode value )
ShadingMode get_shading_mode ( )
Sets whether the shading takes place, per-pixel, per-vertex or unshaded. Per-vertex lighting is faster, making it the best choice for mobile applications, however it looks considerably worse than per-pixel. Unshaded rendering is the fastest, but disables all interactions with lights.
Note: Setting the shading mode vertex shading currently has no effect, as vertex shading is not implemented yet.
bool shadow_to_opacity = false
If true, enables the “shadow to opacity” render mode where lighting modifies the alpha so shadowed areas are opaque and non-shadowed areas are transparent. Useful for overlaying shadows onto a camera feed in AR.
SpecularMode specular_mode = 0
void set_specular_mode ( SpecularMode value )
SpecularMode get_specular_mode ( )
The method for rendering the specular blob. See SpecularMode.
Note: specular_mode only applies to the specular blob. It does not affect specular reflections from the sky, screen-space reflections, VoxelGI, SDFGI or ReflectionProbes. To disable reflections from these sources as well, set metallic_specular to 0.0 instead.
bool subsurf_scatter_enabled = false
If true, subsurface scattering is enabled. Emulates light that penetrates an object’s surface, is scattered, and then emerges. Subsurface scattering quality is controlled by ProjectSettings.rendering/environment/subsurface_scattering/subsurface_scattering_quality.
bool subsurf_scatter_skin_mode = false
If true, subsurface scattering will use a special mode optimized for the color and density of human skin, such as boosting the intensity of the red channel in subsurface scattering.
float subsurf_scatter_strength = 0.0
void set_subsurface_scattering_strength ( float value )
float get_subsurface_scattering_strength ( )
The strength of the subsurface scattering effect. The depth of the effect is also controlled by ProjectSettings.rendering/environment/subsurface_scattering/subsurface_scattering_scale, which is set globally.
Texture2D subsurf_scatter_texture
void set_texture ( TextureParam param, Texture2D texture )
Texture2D get_texture ( TextureParam param ) const
Texture used to control the subsurface scattering strength. Stored in the red texture channel. Multiplied by subsurf_scatter_strength.

The intensity of the subsurface scattering transmittance effect.
Color subsurf_scatter_transmittance_color = Color(1, 1, 1, 1)
The color to multiply the subsurface scattering transmittance effect with. Ignored if subsurf_scatter_skin_mode is true.
float subsurf_scatter_transmittance_depth = 0.1
The depth of the subsurface scattering transmittance effect.
bool subsurf_scatter_transmittance_enabled = false
If true, enables subsurface scattering transmittance. Only effective if subsurf_scatter_enabled is true. See also backlight_enabled.

Texture2D get_texture ( TextureParam param ) const
The texture to use for multiplying the intensity of the subsurface scattering transmitteance intensity. See also subsurf_scatter_texture. Ignored if subsurf_scatter_skin_mode is true.
TextureFilter texture_filter = 3
void set_texture_filter ( TextureFilter value )
TextureFilter get_texture_filter ( )
Filter flags for the texture. See TextureFilter for options.
Note: heightmap_texture is always sampled with linear filtering, even if nearest-neighbor filtering is selected here. This is to ensure the heightmap effect looks as intended. If you need sharper height transitions between pixels, resize the heightmap texture in an image editor with nearest-neighbor filtering.
bool texture_repeat = true
Repeat flags for the texture. See TextureFilter for options.
Transparency transparency = 0
void set_transparency ( Transparency value )
Transparency get_transparency ( )
The material’s transparency mode. Some transparency modes will disable shadow casting. Any transparency mode other than TRANSPARENCY_DISABLED has a greater performance impact compared to opaque rendering. See also blend_mode.
bool use_particle_trails = false
If true, enables parts of the shader required for GPUParticles3D trails to function. This also requires using a mesh with appropriate skinning, such as RibbonTrailMesh or TubeTrailMesh. Enabling this feature outside of materials used in GPUParticles3D meshes will break material rendering.
bool use_point_size = false
If true, render point size can be changed.
Note: This is only effective for objects whose geometry is point-based rather than triangle-based. See also point_size.
Vector3 uv1_offset = Vector3(0, 0, 0)
How much to offset the UV coordinates. This amount will be added to UV in the vertex function. This can be used to offset a texture. The Z component is used when uv1_triplanar is enabled, but it is not used anywhere else.
Vector3 uv1_scale = Vector3(1, 1, 1)
How much to scale the UV coordinates. This is multiplied by UV in the vertex function. The Z component is used when uv1_triplanar is enabled, but it is not used anywhere else.
bool uv1_triplanar = false
If true, instead of using UV textures will use a triplanar texture lookup to determine how to apply textures. Triplanar uses the orientation of the object’s surface to blend between texture coordinates. It reads from the source texture 3 times, once for each axis and then blends between the results based on how closely the pixel aligns with each axis. This is often used for natural features to get a realistic blend of materials. Because triplanar texturing requires many more texture reads per-pixel it is much slower than normal UV texturing. Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.
float uv1_triplanar_sharpness = 1.0
A lower number blends the texture more softly while a higher number blends the texture more sharply.
Note: uv1_triplanar_sharpness is clamped between 0.0 and 150.0 (inclusive) as values outside that range can look broken depending on the mesh.
bool uv1_world_triplanar = false
If true, triplanar mapping for UV is calculated in world space rather than object local space. See also uv1_triplanar.
Vector3 uv2_offset = Vector3(0, 0, 0)
How much to offset the UV2 coordinates. This amount will be added to UV2 in the vertex function. This can be used to offset a texture. The Z component is used when uv2_triplanar is enabled, but it is not used anywhere else.
Vector3 uv2_scale = Vector3(1, 1, 1)
How much to scale the UV2 coordinates. This is multiplied by UV2 in the vertex function. The Z component is used when uv2_triplanar is enabled, but it is not used anywhere else.
bool uv2_triplanar = false
If true, instead of using UV2 textures will use a triplanar texture lookup to determine how to apply textures. Triplanar uses the orientation of the object’s surface to blend between texture coordinates. It reads from the source texture 3 times, once for each axis and then blends between the results based on how closely the pixel aligns with each axis. This is often used for natural features to get a realistic blend of materials. Because triplanar texturing requires many more texture reads per-pixel it is much slower than normal UV texturing. Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.
float uv2_triplanar_sharpness = 1.0
A lower number blends the texture more softly while a higher number blends the texture more sharply.
Note: uv2_triplanar_sharpness is clamped between 0.0 and 150.0 (inclusive) as values outside that range can look broken depending on the mesh.
bool uv2_world_triplanar = false
If true, triplanar mapping for UV2 is calculated in world space rather than object local space. See also uv2_triplanar.
bool vertex_color_is_srgb = false
If true, vertex colors are considered to be stored in sRGB color space and are converted to linear color space during rendering. If false, vertex colors are considered to be stored in linear color space and are rendered as-is. See also albedo_texture_force_srgb.
Note: Only effective when using the Forward+ and Mobile rendering methods, not Compatibility.
bool vertex_color_use_as_albedo = false
If true, the vertex color is used as albedo color.
Method Descriptions
bool get_feature ( Feature feature ) const
Returns true, if the specified Feature is enabled.
bool get_flag ( Flags flag ) const
Returns true, if the specified flag is enabled. See Flags enumerator for options.
Texture2D get_texture ( TextureParam param ) const
Returns the Texture2D associated with the specified TextureParam.
void set_feature ( Feature feature, bool enable )
If true, enables the specified Feature. Many features that are available in BaseMaterial3Ds need to be enabled before use. This way the cost for using the feature is only incurred when specified. Features can also be enabled by setting the corresponding member to true.
void set_flag ( Flags flag, bool enable )
If true, enables the specified flag. Flags are optional behavior that can be turned on and off. Only one flag can be enabled at a time with this function, the flag enumerators cannot be bit-masked together to enable or disable multiple flags at once. Flags can also be enabled by setting the corresponding member to true. See Flags enumerator for options.
