When I animate the smartbones with the regular bones (like the arms etc.) the animation gets shaky. However if I only animate the smartbones the problem doesn't occur.
I drew the character vectorel in moho.
I could share the document too. I'm new at rigging and just couldn't figure this out. Please help me, thank you.
