I need help figuring out how to move the fingers on a model

I downloaded this model a while ago and I don’t remember the author so I can’t reach out and ask about how it was set up. I’m still pretty new to Blender, but I’ve been trying to figure out how to make the fingers bend on this model. I’ve looked at the custom properties or constraints, but maybe I was looking in the wrong places cause I couldn’t do it. Could someone help me please?

Welcome to BA :slight_smile:

Moving the fingers looks to be done by scaling or roating these orange bones on layer 6:

Please be aware that the bones for the arms appear to be oversized, so scaling it down a bit and making sure the bones are in the right place will help fix the bad deforms:


The legs have the same issue

Thank you so much! I didn’t really get where the layers were coming from and didn’t noticed they were also hidden
