I'll post a comparison when your material has finished rendering. From 
what I can see your texture looks much better. Mine finished in 10 
minutes and after 20 minutes yours is 18% finished.

I think it needs higher subsurface { samples }

In the meantime I posted the DFX mesh in povray.binaries.misc in the 
thread Lamp with SSLT Figure, if you want to try it. (3 Megs)

It's coming, it's coming! Dev team colleagues did agree to include it 
even in the next 3.7.0 release candidate!

I can't wait to see what you guys will make of it...

With your artistic talent you shouldn't need to wait. ;-)

I don't know what order these images will be posted but yours is the 
lighter one. I think that for this model the agate pattern is 
superfluous. But more discussion might be wasted with Clipa's news.

Just curious, how many POV-units is the model in your scene? After I rotated
VickiLamp and ran her through PoseRay it shows:

size dx,dy,dz=(0.192059,0.631494,0.42944)

So I just used scale 1.59 to make her 1 POV-unit tall. Assuming she's about a
foot tall as a lamp I changed my mm_per_unit to SSLT_UNIT_FT and got this result
after 13 min. (using the same samples of <16, 8>*8). The SSLT is subtle but
really makes a big difference when comparing left to right.

Good question, I make it 16.5, after scaling. But I said to my self if 
it were standing straight it would be about 20 and the height 10 inches. 
This gives mm_per_unit = 12.7 but for some reason I've been using 
mm_per_unit  74.86

It took me about 40 mins to render her with your material 10 mins with mine.

Width = 800
Height = 600
Antialias = On
Sampling_Method = 1
Antialias_Threshold = 0.300
Jitter = Off
Antialias_Depth = 3

It does indeed. :-D
I'm playing with the Stanford Bunny ATM.

Not really: I keep getting distracted by things to fix & improve in the 
code :-)

Better than being distracted by hunger and poverty. ;-)
