Incorrect bounce behaviour of bullet solver 2015年2月10日9:19

This is not a feature, but a side effect of the parallel solver. You can check the documetation:

However, the multi-threaded constraint solver behaves differently than the single-threaded constraint solver in several ways:

The Split Impulse and Penetration Threshold parameters are not supported.

Objects tend to lose less energy in collisions versus the single-threaded constraint solver.

Instead try to play with physical parameters of the ball and the ground. There is a bounce parameter.

Thanks for response.
So what is the best solution for simulating this kind of stuff? Set off multi-threaded constraint solver and crank up bounce parameter in physical tab?

Incorrect bounce behaviour of bullet solver 2015年2月9日18:25

Hi.
I'm trying to drop a ball on the floor and i want some bounce happen. I made sphere and rbd object from shelf. With default settings, ball doesn't bounce at all (bounce set to 0.5). If i set “Use Parallel Constraint Solver” checkbox on, i'm getting nice bounce, but i also get big padding between floor and ball.
So my question is how to make nice bounce without huge padding between objects?
Thanks!
