Would a collision model around the player work for clipping?

Namely, to prevent people from putting their heads into places where their heads should not be going (due to positional tracking)? Or would you just need to create a larger collision model (say, 3m away from the object) so that the player cannot get close enough to put their heads into the wall?

Even then, let’s say the “object” in question is an NPC (or another player), how would you handle the collision model for that?

Ugg, first world problems are the worst :\

fade to black, there are another thread about that, and check the VR template have implement that (but not work fine still can see through walls)
