@bxrry_bugzz best thing you can do here is to copy all the materials into a new folder and change them into vrchat/mobile/toon standard shaders. afterwards add "quest" to the end of each of the material's names to differentiate them. then make a duplicate of the avatar and swap the materials to your new quest materials. Once you've done that you can use per platform override to upload both of them to their respective platforms. Also if the quest version of the avatar goes above the 10mb limit find the textures and use android override to reduce the max size of the textures to like 1024 or 512.
