All Implemented Interfaces:

LightmappedShape

public class LightmappedTriangle
extends TexturedTriangle
implements LightmappedShape

A textured triangle whose texture is a GI-generated lightmap composite (baseColor x lighting). UVs are fixed at (0,0), (width,0), (0,height) (engine UVs are in texture pixel units): the whole triangle is covered by its own lightmap, valid region u+v <= 1 in normalized coordinates.

Shading via LightingManager does not apply — all light (ambient, direct with shadows, indirect) lives in the composite texture, which the GI system regenerates and swaps in every few sweeps.
