Hi Doran, I don't know how I missed your post earlier. Apologies for the delay. It looks like there are a couple of IK bugs in this release version of C6 that weren't there in some of the earlier beta's. I've reported some and I know that there are others as well. I know that the bugs are being squashed as we speak but that doesn't make it eaiser to use in the short term. I've re-built some IK chains myself for an assignment but if you're patient and don't need to create an animation right away, you might want to wait just a bit and let a couple of things get fixed. The first patch is scheduled for this month but are a few days left before the 30th... :-/ Mark
