Unwanted ground collision

Decrease the Timestep value, to 1/4 or less in Tyflow icon.

Thanks,

In the meanwhile I ran a simulation with modified PhysX values. I doubled both substeps and Pos Iteration values. It was much better. Next I will test Your suggestion.

When using PFlow with Phys X, the ideal substep value was 3. The bigger the value, more unexpected results I got. In tyFlow it seems to be different.
