How do I make a mesh deform only due to collision and not movement?
I have a complex mesh, and my goal is to have certain parts of the mesh deform while the rest stay rigid, and I need those deformations to happen only on collision with another object.
I'm currently ...

Collision “Thickness Outer” and “Inner”
When you look at the Collision settings in Physics Properties, you’ll find Thickness Outer and Inner. I understand that Outer is an option to detect external objects like Cloth and SoftBody.
However, ...
