You can use a tool to export things from kotor as an .mdl file. You can replace models and textures easy enough it seems. No idea if the resolution can be increased. I assume that since you can replace the model you can replace the UV map too so it works.
Maya can't import mdl files it seems. Currently looking for a way to change the mdl to something else. I think this is different to the Source engine mdl file.
Okay, I figured out how you import models from KoTOR. You need a tool to first access the .bif files which is an archive of every model file in Kotor. Once you do that you double click on a model to export as .mdl. This file can be imported into 3ds Max using a plugin made for modding certain Bioware games. Problem here is Max sucks (you can of course export to obj so you can use Maya but I think you lose everything but the geometry) and a program that sucks is not a good thing to use..
