Ok, I see the problem you are running into. I use milkshape 3d to re assign uv maps but the method the artist used is called 'tiling', which is only possible with multi textured models. An example is that the walls stretch from one end of the corridor to another with only a square. The only way to do this propperly would be to break the model down into multiple pieces, but that would take up much more memory than you are looking to. The better way would be to make the 2 models as I mentioned before= one dynamic with multiple textures and no collision, and one static with an invisible single texture for the actual collision. Sorry it couldn't be easier than that.
