Rigging monster back leg with proper ik till the bottom?

Hey guys. Here is another question from me. I bet, some of you did this before…
If anyone could help me with this, i would be glad. Thx


thx. that what i need…

Here is my current progress on the rig. I used Lee’s tutorials for the rigging from Cgmasters.net. I’ve got ik/fk arms and legs. Wrote from the lesson a script for layers. Very nice tutorials. In a future, i am planning to adapt script for snapping arms and legs between different modes.
