Lightmapper

Inherits: RefCounted < Object

Inherited By: LightmapperRD

Abstract class extended by lightmappers, for use in LightmapGI.

Description

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

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