@hborre how is the color ramp in Poser 13 broken compared to Poser 14?  During Beta testing of P14 we found that if you don't have flags/pointers at the 0 and 100% points then weird color artifacts would occur.  But if you put in a start point at Zero that is the same color as next point up the scale say at 40% then the artifacts don't show up.  Not quite the same as moving the bottom point up to 40% leaving the bottom open like you find in the Blender tutorials but it does work.  However, the Poser color ramp is still very limited compared to Blender or my Expandable Color ramp.  Other than the fact my color ramp does not do the spline curves it is better in that you can change the blend type between each pair of points on the ramp. The helper node is just a set of constant values to feed into the Blend type to choose how to make the ramp behave.  The other difference is that you have to feed in the % point for each color point instead of clicking on the ramp and having it auto fill.  One other advantage is that my ramp allows you to put in any other node (within reason) as the color to be filled, Blender has something similar.
