https://vrcmods.com/item/2373These are just replacement meshes so you wont need the modded SDK, but your package is still required, only FBXs. You will also need to toggle off the crown to pass the limit.
there is an extra head in her head, I'm sure if that wasn't there it would be way less polygons. or if it could be toggled out. Its cool and all but promoting the modded SDK is just going to get casual players banned for it.
