    In a post here a few weeks ago, I mentioned that I have worked up a new version of the IK expression that seems to work well for most applications. I really try to avoid pimping my site in this forum, but since it was discussed here I thought I should point out that I’ve added a new IK write-up (for those interested in this kind of stuff):

    Dan, great stuff. Soooo… much easier to setup than the first version, I just had to be carefull with layer names (always a minor problem for me and expressions). And the hands and feet stay connected, excellent.

    Bigfoot thanks you, he’s moving better now.

    Thanks Mike. It’s always a good idea to keep Bigfoot happy.

    It’s not pimping when it’s honest work. Besides, free “copy and paste” is a far cry from “five-dolla make you holla”… ☻

    EXELLENT, very nice, very smooth, lot of control and a very ease to follow tutorial even for a beast like me. I olso have a question by the way, let’s asume that my character is dancing, when his feet touch the ground how can i make them stay in the surface instead of going through it. The movement is nice, but i am having a lot of trouble with this, can it be fixed by an expression ?. Anyway, i am very thankful for the knowledge you are sharing and the way you are doing it, it’s a great work.

    I am having real fun with this expression and set up. And one issues. I needed to rotate one “limb” prior to parenting and adding the expression. It behaves oddly. The lower limb rotates around the anchor point of the upper limb. Is it necessary for all “limbs” to have a zero rotation?
