Well,if i have made a map using milkshape3d, how do i set the wall or floor to a solid object?(means player canot walk through it) or those passable objects?
That post should help you out. It makes no differents if you use a q3bsp mesh or a 3ds mesh. If your mesh is quite big you should create the specifc triangle selector for it, check out the api docu.
