I have a cube with a box collider (trigger off) and rigidbody (use gravity on, kinematic off, collision detection discrete) and it falls through my plane, box collider (trigger off) and rigidbody (use gravity off, kinematic on, collision dectection discrete.
Have you tried it with kinematic off on the plane? Also have you looked onto your colliders? They could be to small/etc. Maybe give us a few screenshots to show your problem.
I think I have tried that but I’ll give it a go. I’ll post some screenshots too.
UPDATE: So setting is kinematic to true did not work. Just to go more into depth it is just the car and the cube that fall through the plane. The player is using a NavMeshAgent and has is kinematic to true.
If you’re using NavMesh then it’s the agent in control of the movement, not physics.
There’s a dedicate NavMesh forum here. I can move your post if you like?
No its okay thank you, the issue is with the plane and and objects falling through.
