I did think it was going to be a simple rig, but it looks super complicated now haha.
Bendy bones don’t play nicely with curve objects (only real geo). But you want to keep those cable as curve objects. It’s going to make things easier in the long run. Hooks and curves are the way to go for these types of cables.
It might be possible to have the Hook bones stick to a bendy bone with an armature constraint – I haven’t rigged anything that way before but I think it would work nicely. (for the cable sections that are between the arm segments and need to bend).
But that also might be overkill.
I’m happy for Shawn to rig it and I can help if he gets stuck.
