I made sense? And I've got it in writing! Wow! Now the 'trick cyclists' have GOT to believe I'm no longer a threat to society. Anyway .. couple of other IK related issues, specific to P5 (P4 handles this stuff so much better). If you've got a memory intensive scene, IK in P5 can lag behind what you're doing. Sometimes you may notice long streaks in your window that stretch from where the end point of the chain WAS, to where you've moved it. Nudge the camera and the scene corrects itself. The other thing is if you resize a body which contains an active IK chain and then pose the IK'd limbs. The limbs can look really odd, adopting strange sizes and proportions. But render the scene and they appear as you'd expect them to. It's only happened a few times and I can't recreate it at will, but it IS damned strange. And if someone from CL happens across this thread, my wish for P6 would be a proper chain-break for IK chains. So if you've got a long wiggly limb with several IK'd actors in it, you can click halfway along the chain to break it, but leaving the second half of the chain intact, with the mid-point as the new IK goal. That would be so cool and, I suspect, not that hard to incorporate.
