I have a Rigidbody3D, let’s call it Bob, that has a linear velocity of Vector3.down.

This Rigidbody3D is on top of another Rigidbody3D, let’s call it Alex, which is a regular Rigidbody3D. Both of them are on top of a StaticBody.

What happens is that Alex is going inside the StaticBody, but what I want is for both Rigidbodies to remain stationary.

How can I achieve this?
