Help cloth passthrough

[danazoid]

In a two-way coupled setup, as tension increases, cloth starts to apply a force on the forceps that's equal to the force you're applying to the cloth while pulling. Once both forces cancel out each other, neither the cloth or the forceps are able to move.

Do I need to enable 2-way coupling in Obi?

My VR setup is just XR interaction toolkit, and the forceps are held using "velocity tracking" mode. The forceps doesn't go through walls and gets pushed back.

Correct. When you pull the cloth, at first particles move normally and there's not much tension in the links between them. If you continue pulling, at some point tension starts to become too much and particles start separating from each other, opening gaps in between them trough which colliders can pass. The size of the gap vs the size of the collider determines whether the collider can pass or not.

Naively asking: are there any sims that avoid the elastic pass through problem?

In this case, surface collisions will help. Surface collisions improve spatial sampling, as long as the tension forces involved aren't large (and they won't be because cloth is compliant) collisions will work fine.

The last time I tried surface collisions it didn't work and the skin started to er... spike.
But for some reason I can't reproduce the problem and it works great now! Huh.

Thanks for help!
