Maybe there's a way to replace this arms with the wings ? Or combined them ?
It'd be the easiest way to fix the issue, (and be more accurate to the original classic succubae), but I wanted the model to remain as it was.
The perfect scenario would be me editing the animations to stop the arms from flapping, and making the wings flap more.
It's a lot of work, but seeing how a winged humanoid would be a very useful model, I'll be playing around with it.
Can't promise anything soon, unfortunately.
