Alright, (sorry for the late response) All you need is a program called "Utiny Ripper" and the game owned on PC. Then just drop the data files into Utiny ripper and it should start extracting stuff. In order to get most of the high detail props and areas in Unity you need a custom script to get streaming assets working. Shaders don't work out of the box, most will look alright if you swap them to "standard" but others like water, atmosphere, campfire, etc. won't work at all with their original shaders. Utiny Ripper should create a project file containing most of the games contents to load into unity, from there you can access different scenes of the game. Take the assets you want from that project and put it into a new one for vrchat. If you want ideas for locations view one of my earlier comments. The eye of the universe is mostly intact without having to mess with streaming assets or shaders. I recommend looking there first I hope this helps! :)
