class Enlighten::PrecompMeshProperties

Properties of input meshes.

These properties control the behaviour of meshes in geometry objects.

The three flags (direct, indirect, target) control how the mesh is to be used by the precompute. The fourth flag is unrelated to how the mesh is used and controls whether to rescale the UV charts to be proportional to the world space surface they represent. This is on by default.

For the first three flags, only two combinations are allowed.

The default of (True, True, True) means "included in the radiosity computation" and also provides a surface which other meshes can be projected onto. The other option (False, True, False) means "share lighting" and requires there to be at least one other mesh within the geometry object included in the radiosity computation.

Please see the implementation guide for more information.
