Rotation problem with 2 CCspheres
on Oct 10, 2019 at 2:31:42 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.
