Hmmmm... the fBm node is the only node that seems to work for me. 

Here's a screenshot of a simple shader (based on the screenshot in this post from that 'PP2014 Image Map Node...' topic mentioned above, but modified to create an 8x8 grid) with a  FireFly render. The second (unconnected) fBm node is a duplicate of the connected one and has all the same values:

If I leave the material room, change the renderer to SuperFly, and go back to the material room (exit/re-enter required to update the mat room preview) the preview of the connected fBm node looks unpromising, but when I render it seems to work okay:

(I'll do the same with the other nodes tomorrow)

The 3Dcheapskate* occasionally posts sensible stuff. Usually by accident. And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU or something else.
