Ok I'm playing around with the physics system and I got a little ball rolling around that moves according to the arrow keys that's working great. It collides with level geometry fine and looks great but if I try to use a model for like an upward slope it collides into it's bounding box. I thought A6 was using polygon collision so why isn't the physics or am I missing something? I want to use the model for a slope the ball can go up that isn't a possible shape to make in wed (well maybe it is but not easily).

For performance reasons models use bounding boxes by default. If you set the model's polygon flag ( slope.polygon=on; ) the real shape is used instead.
