This is a simple Particle Pack I put together for creating teleport/disappearing FX on your VRChat avatar.
Some pre-assembly has been done for you, all you have to do is assign your avatar's body skinned mesh renderer to the shape under emitter in all particle systems.
WARNING: Some unity knowledge required.

Release 3: Fixed Emitters for optimized Particle count and easier Mesh Emitter assignment.
