Yes, I understand that, but it doesn't solve the problem of two collision trees next to each other, one of them has to move and I can't work around that just by rotating/moving the world or the collisions won't work.

I have to try that though, if I can wrap my head around that concept.
Guess my game engine needs some major modifications too, which may still mean that I'm out of the competition. We'll see...

Anyway, I couldn't even imagine that this would be any kind of problem for a physics engine, guess it's true when they say that Newton is pretty much the worse physics engine out there... Haven't tried any other engine though, I downloaded some and there's mostly just C source which I can't compile and usually not any kind of Delphi headers either.
