joints flipping in wierd directions

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.
From the far horizons of the unknown come transcribed tales of new dimensions in time and space....

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.

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.
The only thing that your required to do each day is wake up after that everything else is extra credit....
