Default moving IKīs pivotPoint

hi there - I have a quick question about above said.
ARMsetup -> shoulderJoint - elbowJoint (goes about to the middle of the underarm) - forearmJoint - wristJoint. in order to rotate the forearm along its own axis the IK starts at shoulderJoint and ends with the forarmJoint. for more ergonomical handling I need to pointConstraint a locator with the resulting effector where the hand starts of. that for I have to snap-move the IKīs pivotPoint to the wristJoint.

hereīs the problem. it is a known bug with maya 5.0. after moving the IKīs pivotpoint to another joint the thereīs an updateproblem. but right after grabing the IK again and moving it the scene gets updated - no problem.

I work with maya 6.0 and my scene doesnīt get updated. the pivot jumps back to itīs origin every time. after struggling 1 hour with the IK and pivot it suddenly worked out. but the pain in the ass is, itīs neither reproducable nor is it possible to mirror the jointchain including the IK correctly. I donīt even know why it worked out once.

maybe someone has encountered this occurence too and has something to tell about.

cheers!

the answer came within the question if anybody likes to know.


create IK. go hypergraph. grab effector. snapmove its pivot to some other joint.

happened accidentally in my case. I thought I had to grab the ik_handle and move its pivot -> mistake, canīt be moved.

cheers!
