Uploaded the Freebie now waiting for approval.  Above is Render with 3 Maps on the right.  I have the Map Range on the Torus going from 1-.45 then .45-.7 finally .7-1, which why it has that big spot in the middle.  Below will be the node setup.

Just to show the TO range can go from large to small.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
