POV-Ray [plugin] (updated: 2016/Aug/08)

Micheus,
I did not know that SSLT (SSS) was available in Pov-Ray.

I did a little bit of googling and found the following link interesting: SSLT Finish

Subsurface Light Transport

The subsurface light transport feature, also know as subsurface scattering, is enabled ONLY when a global_settings subsurface block is present. For example, to enable SSLT and use it's default settings, you can specify an empty block.

global_settings {
subsurface {}
}

To activate SSLT for a particular object you will also need to add the following statement to its finish block.

material {
texture {
pigment { PIGMENT }
finish {
...
subsurface { translucency COLOR }
}
}
interior { ior FLOAT }
}

What I found most interesting is that The Bounty (Fork build of YafaRay) uses a setting in the material combined with a setting in the global settings like Pov-Ray does.

I have tried SSLT/SSS in Kerkythea in the past and TheBounty is much faster. Even though SSS is slow compared to other materials.
