Incorrect TreeCollision?

Hello,
I'm having problems with a treecollision from a specific mesh (didn't found problems on any other until now).

(the white lines is the Newton debug)
The top part of the table (surface?) it's not "collidable"! Bodies only collide with that line that goes from one edge to another...

I've already tried doing it from reverse face winding...
Any idea?

EDIT: Found that if I don't set optimize to true when creating the treecollision, it seems to work... need some more test tough...

Hmm, which version do you use Newton 2?
But for questions about optimisations you have to ask in the Newton forums...

Zero

Newton 2.03... I'll ask there then... thanks
