After looking at your post(again) you suggested I use another physics engine. For some reason, the camera (apparently) has it’s own, So you can’t. I’m not the best at explaining this, but here is a previous post of mine and it might help explain it better:https://forum.babylonjs.com/t/physics-dont-work-with-the-collisions-demo/1409.
Thanks for the idea, though.
