This is my latest skeleton incarnation. Thought I would post a picture and hopefully get a file up in case someone wants to play around with it. I’m using pointer bones at the end of the IK chains bent 90 degrees which helps the chain bend the right way when you grab it in automatic IK mode. I’m sure none of this is new or anything, but it’s kind of new for me.
Here’s the blend in case you want to try it.
