This is a MODDERS RESOURCE
Heres a tool to extract levels out of kotor and TSL. If you need to covert the models you could use a converter like 3d object converter. Not shure if these would work in game after edit and conversion but its worth a try.
NOTE:This is slightly different from glintercept.....
This is the OpenGLXtractor Windows Tool!
With this tool, it is possible to Capture 3D Data from an OpenGL Application.
Like 3D Mesh, Textures,Shaders,UV's,....and more.
