dynamics issue

[Tom Ma]

I have a dynamics setup with a bouncing ball on a ground plane.
All is working correctly, but on contact with the ground plane at an angle, the ball does not rotate as it should (on impact/friction with the plane)

I have tried all types of collision settings in rigid body dynamics tag. not working..

any idea how to make this work?

if you have the friction settings on either the sphere and/or the ground too low there might not be enough friction to get it to rotate. Or if the Rotational Mass on the sphere is way too high it won’t rotate either. Though if you need low friction you can set Rotational Mass very low…
