Hi Fred!
Have you worked with the CAT rig system in Max (I'm in 2012 currently) and have any pointers or advice on the FK/IK snapping problems? I'm just working with the default human rig in CAT and the FK/IK snaps STILL don't work correctly... they seem to have some kind of rotational offset that doesn't line them up properly. Thoughts?
Thanks for any insights!!

I havnt used CAT much at all. We tried to use it for a project and realized that the animation file wouldn't reference properly into a lighting scene. Fuck that shit. I need my TD and animator to work at the same time. I tend to stick with simple rigs so we can trouble shoot them. Autodesk is pumping more money into CAT so maybe they will work all these problems out. You might want to report the problem to the wishlist section of the Area at Autodesk. Don't assume someone else has reported the problem.
