Lightmaps
Many 3D game engines support lightmaps.
The effect of direct illumination and ambient light on individual objects can be expressed using lightmaps as textures.
A mapping pattern, image, vertex color, and other baked mapping can be used as a lightmap.
Direct illumination and ambient light do not require rendering, reducing rendering time.
