Like in the title, I'd like to have a master controller that control 2 other controller together BUT I want that those controller still remain controllable indepandently. But that's not over, 'cause these "child" controller are already in an arborescence and are link with the character's joint.
In other words (thanks to the picture ^^), the yellow controller must control both red and white controller (expect for the arms).
I've already tried several thing like the parent constraint (but when I select one of the child controller, it doens't care about the arborescence) or even to link the controller with the connection editor (but, here, the child controller don't move anything, everything stay fixed). And when I was putting them as parents, it moved but there was a shift.
Thank you very much for your help.
Hope I was clear enough. =)
