View Full Version : BIIG rotation problem

Or not so big for you experts.
The picture will show you all. I have a wrist control which controls whole wrist including rotation. The problem is that whe i select frist control and then select frist joint and rotate in let's say z axis two of them rotate in totaly diferent directions.
I have this problem since ever and now i decided to find it oput, so please help me.
Thx in advance
Check the rotation axis of that "first joint"... The Z axis is not matching the Z of the wrist control, it is oriented in a diferent direction, and when u rotate (the rot tool set to local space) they move in different directions. U can use the "Local Rotation Axis" component mode to change the rotation axis of the joint to match the wrist control... Hope that helps... :))

ok so u got a "WristCtrl" circle
-group de circle to itself, call if for example "WristCtrlGrp"
-move the pivot of the group to its center.
-freeze transform ..
all of the group's attribute should be at 0 (and all scales at 1)
the original circle (WristCtrl) should also be "freeze transform" .
orient the axis of the circles like you did, so the Z axis is up. (in Maya Y is up, but doesn't matter now)
now when you rotate WristCtrl, the joint should rotate the same way.
(make sure you connected in a way, the joint to the circle)
You don't need to key the WristCtrlGrp, it's just made to go pass this problem.
let me know if you need more help i'll post a screen of the hierarchy you should have.
