Hi!
I've gotten the arm rig to work ok but I'm having a lot of trouble making the upper arm 01 tweak work. The rest of them seem to work perfectly fine and I've gone through the PDF several times, bone by bone. I know I'm probably missing something but I just can't find it.
It looks like the copy_transforms constraints on the middle tweak MCHs are targeting the wrong versions of the bones.

Thank you so much, that makes sense. After a while mch, def and control bones start blending together. I guess I had to re-read the schematic a 5th time.
I'm sorry about the naming convention, you already told me about that at the begining of the lessons but my brain works the other way around so it makes more sense in my head. 😅
