IK is proving to be the most troublesome part of the process so far. [Just when I thought I was home free!] The .pdf manual is quite clear about (1) Select the hip bone/joint with the Select Tool, then (2) use the IK Tool and click on the toes. Carrara does the rest. [Hah!] Then I tried it according to Nicholas86 and used the IK Tool to select the toe, then the ankle, then the shins, all the way up. In both cases, when I try to lift the IK Target Handle, the leg becomes a scrambled mess.

But, reaching back into memory, I seem to recall that once IK is applied, it cannot be taken off, or over-written, unless you detach the bones fron the mesh and start afresh. Is this correct? Anyway, the eyeballs seem to have sunk into the mesh, so I have to go in and get them back in place.

ominousplay: for you I articulated the lower jaw. I think Beast will have to vocalize a bit, tho' I don't think razor sharp teeth are in the cards for him.

Thanks for all the feedback so far.
