Perhaps extracting the models and importing them into 3Ds Max or Gmax might reveal some clues on how the models are constructed. Plus you'll also be able to use the material palette in Gmax or 3Ds Max to know what textures are being used.
It's pretty odd sometimes, but the kotor games mostly use the same texture plastered everywhere
But there are exceptions, which ofcourse are very suprising to discover.
Any idea what the model names are for this area. I'dd be willing to reconstruct in Max.
Don't feel like modding my own stuff anyway at the moment
