Is it time to set up IK chains? Yes, I'd say so. IK chains are created within Poser's Hierarchy Editor. Scroll down to the bottom of the hierarchy list and select the element that says "IK Chains"; the "Create IK Chain" button will now become active, and you can click it to create a new chain. Give the chain a logical name like "Left Leg". Once you've created a new chain in the hierarchy list, you can drag-and-drop body-parts onto it. Start with the top of the chain (thigh or buttock) and gradually work your way down to the end of the chain (the foot).
