I’d like to know if it’s possible to lock the position of the foor bones in an armature to the floor so that they don’t move when the rest of the armature does.
I’d still like to be able to move them individually, though.
Can anyone help with this? Thanks.
Do you know about IK constraints?
Yes I do know about IK constraints and I’ve been experimenting with them, but I can’t seem to figure out how to to this particular task.
How are you moving “the rest of the armature”? If you’re moving it in Object mode, then that’s likely part of the problem. Even IK-constrained bones will move with the armature when it’s moved as an Object, if their constraint targets are bones in that armature. You can create IK targets that are external to the armature, but that brings along its own set of considerations.
Perhaps the most common method is to create a “Master” or Root" bone whose sole purpose is to move the entire rig in Pose Mode. Portions of the rig you want to move all at once are parented to this root bone, either directly or through a parent/child bone hierarchy. Bones like IK targets can be left unparented and will not move when the root bone is moved, so they can be used to “pin” the extremities or any other IK chain termination bone.
Hey thanks. I think it’s working. I created a bone in the armature separate from the hierarchy and set it as the IK target. I was up to this point using external objects as pole targets, but I think I’ll replace them with bones.
Thanks again.
Not to be self promoting, but if you still have issues, the following blend has a very simple rig with IK constraints that are pretty straightforward, you can check it out to see how I set it up.

Pretty rad, daren. I’ll check it out for sure.
BTW this is the result of the rig : http://www.youtube.com/watch?v=HFmZVbiIa_w
