There is a big problem that I have due to a recroom mechanic that I hate a lot.
It's a multiplayer game with vents in it. The problem is that you have to crouch all the way down to get in to the vents, and that causes you to go REALLY slow.
I could fix that by giving the player more speed while they're in a vent, but then the problem is that VR players can still crawl in the vent at normal walking speed, meaning that VR players will be going dangerously fast.
I also had the idea of making the bottom of the vent have no collision so people can just walk through the vent like normal, which also allows teleporters to play.
But then, people can just crouch down to make themselves invisible
