I was modelling an excavator and while rigging it, I crashed into a problem, I dont know how to do the last part of rig. I have tried everything, look at constraints, bones, IKs. And I have no idea. I got the hydraulic systems working but this is throwing me off. I add there a link for helping picture to figure out what I mean.
I need a rig to have one control to rotate the bucket and the parts attached to it. Any ideas how to do that?
