If 30% aren't using them, it means 70% are That's still a lot of time used with a little impact vs usefulness ratio
Deer → Yeah it's not so great. I like the current one, maybe you could just use the mesh, you don't need to reexport it (Unless you change the UV ofc) Maybe one day I'll find a way to import the armature in Blender, Pyrogenesis is the only engine that likes it. Even unity 3D doesn't work.
