How to Flip Hands?

[sneedbreedley]

When my puppet raises his arms, his hands need to flip so the thumbs look normal. The hands are on separate layers than the arms. Is there an easy way?

There is a way. What you will need to do is set up multiple arms and hands and then use "Auto Swap" to allow CH to swap the right parts when you need them to. The process isn't easy, but the results are. This page and video will show you how to do it. Switch artwork with Auto-swap (adobe.com)
