Resolved VRChat Avatar Import Script

Hello, I'm trying to make an avatar import script for VRChat avatars. I'm using unity 2018.4.20 as that's what the game uses. I want this script to do a bunch of setup stuff every avatar would do, but make it really simple to do and much faster. I'm new to coding in unity and I've tried to research the pieces I need, and I'm getting stuck.

Current Location
Apply a pre-made preset to target.

Any and all help appreciated!
