LightmapGIData

Inherits: Resource < RefCounted < Object

Contains baked lightmap and dynamic object probe data for LightmapGI.

Description

LightmapGIData contains baked lightmap and dynamic object probe data for LightmapGI. It is replaced every time lightmaps are baked in LightmapGI.

Property Descriptions

TextureLayered light_texture

• void set_light_texture ( TextureLayered value )

• TextureLayered get_light_texture ( )

The lightmap atlas texture generated by the lightmapper.

Method Descriptions

void add_user ( NodePath path, Rect2 uv_scale, int slice_index, int sub_instance )

Adds an object that is considered baked within this LightmapGIData.

void clear_users ( )

Clear all objects that are considered baked within this LightmapGIData.

int get_user_count ( ) const

Returns the number of objects that are considered baked within this LightmapGIData.

NodePath get_user_path ( int user_idx ) const

Returns the NodePath of the baked object at index user_idx.

bool is_using_spherical_harmonics ( ) const

If true, lightmaps were baked with directional information. See also LightmapGI.directional.

void set_uses_spherical_harmonics ( bool uses_spherical_harmonics )

If uses_spherical_harmonics is true, tells the engine to treat the lightmap data as if it was baked with directional information.

Note: Changing this value on already baked lightmaps will not cause them to be baked again. This means the material appearance will look incorrect until lightmaps are baked again, in which case the value set here is discarded as the entire LightmapGIData resource is replaced by the lightmapper.
