1) Not too sure how the cull distance would have been changed seeing as I only edited the module MDL, unless that information is somehow stored in it.
2) Map shadows as in lightmaps. I've figured out it will only show lighting effects if the illumation is set at 0 0 0.
3) Trimesh is the NWMax modifier on the mesh which has some options including the illumination.
I manually edited the model adding in more loops while maintaining the original uvw layout. It's using the stock KOTOR 2 texture still.
Yeah I found it is built-in, so I'm trying to replace that module.
