@martijn During my troubleshooting I noticed that if the object started above the planter and I moved it away from the planter and dropped it, the seed would collide with the planter even if visually this did not happen. I confirmed btw, that the seed is moving away from the planter using the inspector.
It seems the issue is related to the way I'm moving the entity (which I am doing this way since I can't figure out how to mimic what I was doing pre spatial 9 in spatial 9). I'm send commands to the entity with coordinates that the entity takes and uses to move itself. During this process, I set the entities rigidbody to be Kinematic and then non-Kinematic when I grab and release. If I avoid toggling the Kinematic boolean, the collision works fine but it's very hard to move the entity due to gravity.
Does Spatial 9 not allow me to make the rigidbodies Kinematic? In order to move the object I would need to be able to change this.
