CGTalk - Maya IK trouble

I'm trying to set up a leg using maya but I'm having trouble with the IK. When I create the ik chain down the leg and through the foot everything seems fine, except for when I translate the root the feet don't stay in one place, they move with it as though it were FK. This defeats the purpose of inverse kinematics.

I've tried it with both RP and SC solvers only to find the same thing happen. Someone please help me because I'm about to soccer kick my computer out the window.

There are a couple ways to do what you want. The first is to make the IK solver "sticky". To do so, open the attribute editor for the ikhandle and go to the IK Handle Attributes tab. In it you'll see a box labeled Stickiness which you would want to turn on.

Another option is to not worry about the stickiness because after you parent the IK handle to a control of some sort, the foot will stay in place. Say, if you create a nurbs shape and parent the IK handle to it to make selecting and moving the foot easier. Generally it's a good idea to have some sort of controller to select and animate rather than directly keying the IK handle.

Hope this helps.
