Guys you can't just convert a map with the method and have it work. For collisions to work you need loads of convex shapes, and with intricate maps like the kitchen or gsf maps it would require possibly thousands of shapes. Even then, the collision with these things is really weird with big shapes, which can be seen when you try to drive a vehicle on the bedroom.
Terrain is a completely different matter as well, you can't really turn it into a dts, and creating collision would be even harder.
