Help cloth passthrough

[josemendez]

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

No, two way coupling emerges automatically between physical objects. This also happens between Obi actors and rigidbodies. All you need to make sure is that your VR hands are using rigidbodies.

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.

In that case they're already using rigidbodies, and all you need to do is adjust cloth mass.

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

All of them when properly set up . This is only an issue when non-dynamic objects (colliders with no rigidbody, or kinematic rigidbodies) interact with dynamic ones. In this situation you get one-way interaction: dynamic objects are forced to respond to non-dynamic objects, but cannot "fight back" in any way so they are forced to stretch (in the case of a softbody, like cloth) or sink/penetrate other objects (in case of rigidbodies).

let me know if you need further help,

kind regards
