Mesh to Volume Modifier

The Mesh to Volume modifier uses a mesh to create a new volume grid. All previously existing volume grids on the volume object are discarded. So this modifier is usually added to an empty volume object. The new volume grid is called “density”.

Tip

To copy and move the generated volume separately from the mesh object, use a collection instance.

Options

The Mesh to Volume modifier.

Object

The mesh object that determines where the volume data will be generated.

Density

Makes the generated volume appear denser or less dense when rendering.

Fill Volume

The entire enclosed volume or otherwise only the voxels close to the surface will get a density greater than zero. This setting is only used when the mesh object is Manifold.

Exterior Band Width

The maximum distance of the included voxels to the surface on the outside of the mesh.

Interior Band Width

The maximum distance of the included voxels to the surface on the inside of the mesh. Activating Fill Volume is similar to increasing the interior band width to a high number.

Resolution Mode

Mode for how the voxel size is specified.

• Voxel Amount

  This allows setting an approximate number of voxels that will be used to represent mesh along its diagonal. When the dimensions of the mesh changes, the voxel size will change as well. For final rendering of animations, it’s better to specify the voxel size explicitly to avoid artifacts.

  Voxel Size

  This allows setting the exact voxel size that will be used. This is idea for rendering when the voxel size should not change between frames.
