Inherits: RefCounted < Object

Inherited By: LightmapperRD

Abstract class extended by lightmappers, for use in LightmapGI.


This class should be extended by custom lightmapper classes. Lightmappers can then be used with LightmapGI to provide fast baked global illumination in 3D.

Godot contains a built-in GPU-based lightmapper LightmapperRD that uses compute shaders, but custom lightmappers can be implemented by C++ modules.
