The title should read: "turn off forever", duh! IK has its uses, but it shouldn't be on by default, methinks. I seldome use it myself, and get sorta tired turning it off. As to why there is a $15 program to do this, Jim is sorry he broke the guy's rice bowl, but a lot of people already knew about this trick. ;-) Incidently, what actually happens here is Poser looks for Inverse Knematics with a "RightLeg" and "Leftleg" name, and resets that to ON when you open a CR2 (but not a PZ3, if I recall). Any IK by any other name doesn't get touched. This DOES work incidently, all the characters and figures I sell or give away have had it off for years and years. And your welcome, guys!
