View Full Version : joints flipping in wierd directions

06 June 2008, 06:20 PM
im pretty new when it comes to ... anything in maya

building a skeleton and attatching iks to em seems easy enough
but im having much difficulty figuring out how to stop my limbs from
bending/flipping in wierd directions

some assistance?

Before adding the IK, go in and rotate the joints in the direction you want them to bend in. RMB>Set Preferred Angle. Don't undo the rotation, type 0 in the rotation in the channel box after you're done. That should fix the weird bending, flipping is a whole other beast. See if that isn't what you're needing though.

Hi dude, see the local rotation axis of the joints, maybe you built them whit wrong rotation. A good advice is that when you create the joint chain, do it whit not prefered angle setup in the creation options box. :thumbsup:

ok ... er ... wait, what?

one person tells me to do it with prefered angle option, the other person tells me not to used prefered angle option

i dunno what to do

i would set your prefered angles for the joints, put your ik in, then use a pole vector constraint.
