IK FK Blending 2004-07-06 - By Jamie McDonnell - Character Rigging / Animation TD
Back
Hi guys
I have asked this once this morning, so please excuse my repeating the question
but I promise it has evolved from earlier...
I gather from reading xsibase posts etc that the IK / FK blending on standard
bones is not great, but does anyone know a workaround that will allow me to
blend between FK of an elbow joint bending back on itself, and an IK punching
motion? All I seem to get is pops and snaps when trying to blend between the 2
motions. I know I could put them on the mixer, but I need a true IK - FK
blender to animate with...
Which led me to set up the 3 chain IK - FK rig, IK chain, Result, FK chain,
expressions as clips on the mixer driving the rotation / roll / upvector angle,
but the 2nd bone in the chain doesnt update until I change the frame...
Any thoughts sure would be appreciated...
Cheers all
Jamie
