Hello. I've tried to use the MPM solver in Houdini 20.5. I wanted to make a snowman who gets destroyed by 3 balls.
The sim with the 3 balls looks cool. Still needs alot of tweaking and a higher res. But the snowman itself bounces alot prior to the balls colliding.
What can I do here? Anyone have any ideas?

The quick and easy solution in many such cases is to only start the sim a frame before collision. This kind of bouncing often comes from the simulation settling down, the constraints/material resistance is fighting against the gravity/external forces.
