Pretty much a little feature that allows you to touch other avatars using a script that creates collides for other avatars. (Assuming they have dynamic bones.) I know this would cause a lot of frame loss for people who use it, but if it were easy to toggle; people who want it can use it and people who don't wont have to use it. This could add a whole new view to vrchat I think and would be awesome for people who have been playing for a long time. And knowing the internet I'm sure something like this already exists, but it would be great to see it as an official feature.
