Does POV have this feature yet, or is it still just an Uberpov thing?

Does anyone know what appropriate values might be for LEGO (Ldraw) models?
Here are the mm and ldu units:

Wow, there are a lot of _conditions_ that need to be met before sss will
work.

And if you don't use the mm_per_unit correctly. An angel with a fiery
sword comes after you. ;-)
You will get a severe finger wagging. :-)

Do you mean 3.7.1? Because that's what it says in my old uberpov scenes.

I tried an old scene that worked properly in uberpov, but I see no
effect in 3.7.0 or 3.8.0 alpha.
Here are my global_settings:
global_settings
{
assumed_gamma 1
#if (Use_Radiosity = 1)
radiosity
{
pretrace_start 0.1
pretrace_end 0.001
recursion_limit 2
count 3
nearest_count 20,10
always_sample off
maximum_reuse 0.1
minimum_reuse 0.001
// no_cache
}
#end
ambient_light 0
// mm_per_unit 0.4
mm_per_unit 1/4000
adc_bailout 0.001
max_trace_level 8
subsurface
{
samples 5, 5
radiosity true
}
}
Here is my finish:
#declare lg_solid_finish = finish
{
ambient 0
#if (lg_quality >= 2)
diffuse albedo 0.9
specular albedo PlasticSpecularity
roughness PlasticRoughness
fresnel on
reflection
{
PlasticSpecularity
// roughness PlasticRoughness
fresnel on
}
#end
conserve_energy
}
Are there additional settings I am missing?

#declare PlasticSpecularity = 1.0;
#declare PlasticRoughness = 0.001;

3.7.0 on my machine. I've not used it much recently.

You need a subsurface {} block in your finish {} block in addition too
the one in global_settings {}.
Remember there are almost always example scenes for features. A
subsurface.pov sample scene ships with POV-Ray. It can also be found
online at:
