It's definitely coming along. :)

For my next trick I decided to concentrate solely on trying to duplicate the nested ellipsoids effect I did in GIMP a few posts back. I realized that trying to use colour would just confuse and distract me, so I stuck to black and white.

The first thing that struck me was that I could use the v (texture coordinate) node instead of just black/white as the Inner_Color/Outer_Color of an Edge_Blend node.

The second thing that struck me was that I could use Bias/Gain* in a Math_Function node to alter the output of the v node as required.

The third thing I realized was that high (>1) Attenuation values in the Edge_Blend node 

I was amazed - just eight nodes (nine if you count the PoserSurface) and it's looking remarkably good to me.

I just wanted to make sure that I don't lose that !

What I have here looks as if it might be good to plug into Transparency, and perhaps a ColorRamp driven by the v node for the actual colour ?

*I still don't really understand what these do

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.
