Squishy blocks

Unity Engine
1

Hey guys. First off, I’m not a programmer, and am learning Unity to better round out my skill set and learn to create games. I’m a 3d modeler and texturer first and foremost, so sorry if this is a newbies problem.

I am creating a physics based game about stackable falling blocks. As the level starts, stacked blocks appear. I want them to appear solid, but right now they appear as if made of tofu (squash and stretch as they land on each other).

I have tried several things, like drag (seems to just slow the descent of blocks), I tried applying a
physics object to it with maximum Friction Combine and minimum Bounce Combine (I was hoping that would work), I tried playing with the mass as well.

I have found a way to stop it, if I make the blocks a lot larger and turn the gravity up, they appear to solidify. I want to know if there is a parameter that I can adjust to avoid scaling everything.

Thanks for your time!

I’m having some similar issues.

Mass is probably the way to go. Drag is air resistance, so it won’t change the behaviour when they hit each other much. The physics material is most important.

But I’m still experimenting myself.

I’ve never seen this behaviour myself, but I wonder if it’s affected by Min Penetration for Penalty in Edit->Project Settings->Physics. That might cause it to behave differently at different scales.
