I know this is old but I was able to edit the mesh on the model to make the wings actually look like wings and adding bones to them to allow for dynamic bones on both the wings and tail. Some pics: http://prntscr.com/n49pbvhttp://prntscr.com/n49pll If anyone is still interested in trying out the model (and maybe favoriting it ;P), my name is "JuansTheName" on VRChat.
Great model, but I don't particularly like the wings. The hand claws also look broken.Would had like to see this model with dynamic bones (especially the tail).
