Head Collision and player height

This is a feature suggestion. I couldn’t figure out how to make them.

I would like the option to be able to have my head collide with surfaces similar to how neosvr does it. (your body moves away from the wall when you try to put your head through, and you cannot walk through objects.

This should be toggled off by default, but the head collision box should be able to collide with polygons above it. this would increase immersion to allow smaller sized players to fit under smaller spaces and require taller users to either duck under them or shrink.
Obviously with the new Udon advances in controlling avatar height, this could be forced off for games like hide and seek so that shorter players don’t gain an unfair advantage, but in vrchat, the option should be available in the same area that avatar height is. In the expressions menu.
