Butterfly Question

Is it cheaper to have 2 bones for a butterfly to flap its wings or use a mono behavior script to flap the wings? I plan to have a decent amount of bugs/butterflies around the game and just would like to know which is cheaper!
Thanks

Best to profile it on your target platform and find out :wink:

Mesh particle with wing texture animation could also be a cheap way yo do it as particles can be batched into much less drawcalls.

How close are they going to be to the camera and how detailed? You could also just use animated sprites and fake it as you might not be able to tell the difference.
