I really tired to see lots of Paimon (character from Genshin Impact) avatars in VRChat without an appropriate cape shader... So, I made my own!
Note that it is not an actual copy of the shader from the game, it's my, let's say, fan-made version, not completely similar, but I tried to make it cool at least!
This shader has a volumetric stars and fog effect, which looks super awesome especially in VR.
