I had a little time to play with SSLT. Yes, Increasing the Samples ("Samples for diffuse scattering: 500") settings under Export Options > Lighting tab > "Subsurface Light Transport" is important for getting a smoother look. I increased both "Diffuse Scattering" and "Single-Scattering Approximation" to the same value to get rid of problems with the material. This setting affects rendering time, so try to keep the numbers as low as possible. It looks like "Radiosity" needs to be set to None. I also noticed that in the General Options tab that SSLT only works with "Quality Settings" set to either Default or Compute Media and Radiosity.
I noticed that when rendering from an angle where one is facing the spotlight I was getting strange squares and lines in the material. I was finally able to discover that increasing the "Anti-Aliasing Threshold" to a higher number (0.9) clears the problem up. I notice that setting the value to 1.0 or higher causes Pov-Ray to crash.
The Threads setting (General Option Tab) does not seem to work at this time, based on what I am seeing in the Povray window where text is displayed.
P.S. I found this link with material settings for SSLT for various real world materials... SSLT Materials
Thanks,
