Hello guys,
I'm trying to take map models .mdl from KotOR 2, modify them a little bit, and put them back into the game. I managed to do it but I get visibility problems: the whole model appears invisible, except for the objects with the glowing material and texture, as can be seen in the image.
I guarantee that the .mdl geometry is there although invisible. In the second image I've removed part of the geometry so that the rest of the map can be seen through.
I guess that this problem could be given by errors with the visibility map or the light map, but I have no idea of how to solve this.
