  Rotation problem with 2 CCspheres

  Posted by Pierre Dubois on October 10, 2019 at 2:31 pm

  Hello!
  I’m trying to make a pac-man head with sticky tooth with 2 CC spheres (head and jaw). But I can’t find a way to open its jaw properly when I turn the head (thanks rotation order).

  Head rotation is linked to a Duik connector, the jaw is linked on head’s values + driven by a null’s rotation.

  Any tips?

  hey thats pretty cool.
  never had to do something like that.
  are both CC attached to a null for master transformation?
  It seems like that’s the issue.
  sorry my angle on that is from years of Maya.

  Not really.
  First CC is driven by a connector from Duik, it works like joysticks and sliders.
  Second CC is linked on the first for X and Y rotation. So it has the same movement. For opening jaw, I add the value of a null rotation in Y.

  It works if the head is in front view. But if I turn the head, jaw doesn’t work. I think it comes from the rotation order of the CC sphere. I think I must use the Z rotation to compensate but I don’t know how.
