Long time user of these forums, first time question, so sorry if I have posted it in the wrong place or what not.
So here we go, I am rigging a character with duik, and I am trying to make a check box expression controller that, when ticked, would make an arm move in front of the body, and when not ticked, go behind. With this I could obviously create some pretty 3d movements. I figure I need an expression that would change the layer placement of the arm based on the state of the check box, but to my knowledge this doesn't exist. Any help you could give me would be awesome.
Thanks so much for the reply. I had tried this originally and it did not work. Perhaps it was something to do with duik or perhaps just a bug in my system, After agonising over it I have found the solution so will share it here in case anyone else is having the same issue. Basically I just copied the arm layer (and all the duik bones and controls, and placed them above the body, Then used a check box control to toggle the opacity of the arm layers between 0 and 100 only revealing the layer I want.
