Hi SFXacidic! The file is ready to simply upload, just drag and drop into unity. If you get the "The following component types are found on the avatar and will be removed by the client: ONSPaudiosource" error try a older version of unity.
Hey Eve! That is a issue on your end not the creator's, anyway to fix this detach the blueprint(Should be under descriptor), reinstall the sdk or make a new scene.
