Render this: SSS
-
When I saw some of the images I just had a crack at it - couldnt believe it when it came out and it wsnt black - where do you guys get all the fabulous materials and how do you store them (what format)

Dermot and Tallguy, nice job rendering, although you are lacking any visible sub surface scattering. The idea behind the thread was to display your favorite render engines ability to perform a SSS (subsurface scatter), which is namely the scattering of light below the surface of a material. Light will usually either pass through an object completely (transparency), pass through and bend (refraction), bounce off (reflection), or absorb (sub surface scattering). SSS is dependent upon the physical density of an object and it physical rate of light absorption. Things in the physical world that exhibit this behavior are wax, soap, skin, milk, plastic, etc. If you notice in all of Solo's renders, you can vaguely see where the light has passed through the outer cube and shown a hint of the sphere within.
It looks like you guys are using Twilight. Try using a SSS template with your materials and use spot lights or emitter lights instead of the physical sky. This will give a concentrated light source which the render engine can use to glean enough direct light bounces to perform the SSS.
Here's a quick test with Fryrender....emitter within SSS.

Next time you ignore kitty, the dog will pay.

THanks obviously I am way off track here. I will try to figure out the SSS system using kerkythea.
Thanks for pointing it out to me. I'm still not sure how to do it but I will try and figure out.
Oh well sorry to clog the thread.

No worries...all in good fun and a method for learning and comparison. Keep on trying and you'll get there before you know it. Wish I could help more with Kerky settings for SSS. Perhaps Miguel could lead you in the right direction.

Sure, I posted some settings here:
http://twilightrender.com/phpBB3/viewtopic.php?f=16&t=356&p=2350Actually, a lot of materials present Sub-Surface Scattering. Just put a strong light behind a slab of marble, a plastic toy, or a china plate. The human body has SSS, too; wax candles, paper, even wood has it. It's just that most of the time it's not that noticeable under normal lighting.
I made two 30-minute renders with Twilight, one with Easy 09 (aka MLT or Metropolis Light Transport) and another with Easy 10 (aka Bidirectional MLT). These popular render methods are also available in Indigo and other unbiased render plug-ins. Spot the differences between MLT and Bi-MLT:
MLT:
Bi-directional MLT:
Here's the file so you can check the settings used:

I actually do, in fact I have a few. But the problem is they are only one material, and the SSS effect is only dynamic with a light behind technique, this way you can have two materials giving more options for SSS and not only the light trick. I wanted to have the option of having another material behind a SSS one, like veins under skin.

hey guys, that would make an awesome preview object for Twilight's material editor!
nice job guys but i think that last one is the cats meow!
-
I think Remus (Indigo), Brodie (Maxwell) and Pete (Vue) have shown the best SSS examples here.

Another try with Twilight's Bi-directional MLT, this time using the plexiglass template for the outer shell.
EDIT: A stacked version of all three previous Twilight Renders (MLT, Bi-MLT and Bi-MLT with Plexiglass) with some post-pro in the cat's eyes.

cool stuff

still cool!

Pretty cool Dermot! I thought you were sitting this one out.....(its pretty fun stuff)

I am using Kerkythea and I downloaded a number of their great material libraries. Since you have twlight I'm sure you have access to tons of materials on their forum.

I looked on the kerkythea forum and found some more info on SSS. (actually today was the first time I ever heard of sss.)

If i'm not mistaken the BPT is better suited for interiors, other way there's no much diference between btp and MLT. You should try the two in a interior room with lighs coming from the windows with real glass just with sun to see the big diferences.

Is this kinda sss?
thanks!
