Environments VrChat Room Of Rain

* Fixed the lighting by entirely removing the mixed lighting and instead opting to use the build in vam lighting. Unfortunately it takes a hit on performance to achieve the same level of realism as the original, I tried to use purely baked lighting, but the messed up UVs don't allow for that.

* Added additional Collision that was missing on some objects. Spawn points are somewhat fixed, I removed the collision where Atoms spawn. Unfortunately you still cannot move the room as all the meshes are combined.
