Hi! Now, I got it working only by setting c_updatehull(ground, 0) every frame.

c_setminmax is not working.

So, is it normal, that I have to use hullupdate when I tilt objects?

All the time before, sphere ball was colliding with plane like plane had tilt 0, no matter what tilt it had in fact.

Also, if I use frame vertex animation for tilting plane, then even c_updatehull stops working.

Anyone had similiar experience or I'm the only unhappy person there?

I tweaked many parameters, gravitation as well. Currently I have got into one other problem. Sphere falls on my plane, bounces 1 time up, and second time it passes the plane with no collision. Like, it bounces with the plane if I place it on z = 200 starting distances, on distances from 100 to 200 it always passes through ground plane. I have normal scaled models, I tryed different geometry (like making box from plane). Do I have to set up something to make collision more percise?
