Hey guys,

I need a rough plastic effect with fuzzy countours of what's behind it. Dielectrics with high roughness do the job, but remain dark and noisy. What about SSS? Where can I find it and how do I use it to get the effect I need?

Is SSS simply the scattering and absorption values? And what values should I use to get it quite transparent?

Thanks very much in advance.

Cheers,

Metin

Hi Metin,

Yes, it is the absorption and scattering values.

Check the reference links here: http://www.maxwellrender.com/forum/viewtopic.php?t=3536

You will find a couple of people made some chatrs about SSS

Thanks Thomas!

I'll check it out.

Cheers,

Ok, did some test renders and Thomas, I read in one of your topics that SSS could be used as an alternative for dielectrics, but I can't get obvious transparency using absorption and scattering. I guess SSS is mainly visible when a light is right next to it, or am I wrong? So the fuzzy shower window effect would only be apparent if the beautiful woman under the shower has a radiant personality.

Next to the above ‘shortcoming’ of SSS as an alternative to dielectrics you would also miss the abbe and IOR settings of course.

Hi Metin,

That would be very interesting, but I can't remember saying it. Where was that ?

.... oh I see what you were refering to ... in that post I was "dreaming" about what SSS should look like and how it *should* behave. It was a theoretical thingy. In other words it would be nice if we could range between SSS and dielectrics in one continuous gradient fashion, because I feel they are both part of the same underlying physical principles.

I get it. Thanks for all your knowledge sharing about SSS. I'm up to date again.
