Is there an option to make a plane above the ground and let the character walk through it, but the camera will bounce of this plane (not flight through) the plane?
Here is my setup: Plane has IgnoreOnlyPawn collision preset
This is probably being caused by how your Spring Arm is set up.
Without seeing the blueprint, I don’t know exactly what settings you’re using, but I’ve found it’s best to use Socket Offset to adjust the Camera position, rather than changing the Transform settings. This seems to give it more stable behavior in general.
I tried replicating your demo in my project, and the camera just slides along the surface rather than poking through it, and those are my settings. It doesn’t bounce, though. Not sure how to do that.
