Lightmap GL madness

Hiya,

I'm currently trying to implement some sort of bump for interiors. It's working fine but I ran into trouble when trying to combine it with the lightmaps. The lightmap was displayed as pink garbage. So I commented all of my bump code out and tried to bind those two textures myself (GL_MODULATE base texture over gInteriorLMManager.getHandle(mLMHandle, instanceHandle, baseName)->getGLName(). I am now seeing the same thing:


Can somebody please explain that to me?

EDIT: Looks like processTriFan() does all the magic. Will look into it.
