Issue with Softbody Collisions

[blobman]

Hi. I'm encountering some issues when trying to collide my softbody mesh with rigidbody meshes. Here is a demo:


You can see, after a few collisions, my rigidbody mesh can get inside of my softbody mesh.

Collider settings on my rigidbody mesh:


Few things I've tried to mitigate this issue:
- Tuning the ObiSolver (using parallel eval. and adding iterations)
- Adding a distance field to the Obi Collider 

both did not work.

Would love to get a better understanding on why this happens and what causes this issue.
