Okay when im using the wings it flies obviously but theres no textures?

This happened to Joey Graceffa with the angel wings i think they were....maybe it could be other mods that are disturbing it.try using just the mod along with the required ones and see or if not maybe one you need a newer version of one of the required mods.

or read other people issues and try fix it from using there info

@EvilEclipse What mods do you have installed?

Some mods to change player rendering in a way not caring for other mod's attachments, so it is out of my control unfortunately.
