Hi I'm new here, I'm a blenderhead. this SSTL feature attracted me to Povray.
What a beautiful piece of software!
My question is whether this mm_per_unit option was added just for SSTL and
applies only to it (which is not clued by the currently chosen keyword) or if
it will also have an incidence over the whole scene's scale and stuff like
photons, radiosity scale etc...?
Using Blend2pov and trying to make a skin shader, my current scale is 1 meter
per Blender Units, and I guess keeping the same in Pov units would make it
easier for me to get more intuitive and predictable results with other Pov
features later. So I tried mm_per_unit 1000 but I could not get the same
translucency with SSTL as I could achieve with mm_per_unit 100, which is indeed
closer to what the algorithm is optimized for.
