it's just a huge part of unity's stuff isn't exposed to udon, so yeah you get arrays but not dictionaries and will have to constantly do simple things the hard way and be angry all the time, but you can do some pretty cool stuff and it's enough features to make real games.

Most of the avatar stuff isn't exposed. That kind of thing takes a modded client which is technically against the TOS (and not enforced unless you're abusing people) but also I think what you want already exists so start by looking though all the client mods before remaking a wheel.
