havent checked it yet, since all i was doing until I got a reply was making a default action to make the object passable.

thanks for looking into it. If i had money right now i'd donate since this is really an amazing contribution. cant wait until we can directly compile wmb's from blender, I wonder if its possible for pro users to manually set up a bsp system, in blender, using the structs predefined in the wmb description, not that I have pro, but it would be interesting to see.
