How we got stuck on Boolean I'll never know and why are we calling Boolean geo-grafting I'll never know that either. Would be so helpful if all the app's called the same tools the same thing.

Anyways if you geo-graft 2 rigged meshes together .Does the rigs n morphs still work ?Does it mess the UV Maps up ?If not you would still have a odd place where the 2 different textures are. you know like a seem. right ? Does normal n displacement maps still work ?
