Render this: SSS

Ecuadorian

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

tallbridgeguy

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!

Torus Knot emitter, inside of ice, inside of honey. FryRender - 15% Isotropic Scattering with 85% Dielectric Transmittance.

TBG - It is to a degree, although it appears to be more of a frosted glass. With SSS you'd expect to see less light absorbed into the thicker areas (i.e. the corners of the cube) and more light absorbed into the thinner areas (those closest to the sphere). In your render you can see the light passing through the thick areas too uniformly to be a true rendition of what SSS would look like. The dark areas in your render appear to be more shadow casting than that of light block through physical density. Keep trying though...you're getting closer.

Thanks for the help! It is an interesting subject and I appreciate the feedback. I have to say it is a difficult subject.

frosted glass and a shiny ball! my god sss takes long time to render! this ones not exactly sss but looks pretty cool!

earthmover: those look sweet! could be ornamental lights!

here's one. . .no idea what I am doing. Just clicking a lot of buttons and hoping for the best.

whaat's wax.. no ambient

we should be using an organic model for SSS:

this is with some fake emitters within rubber ball material, SSS density 0.05

Fair enough, maybe my model is a little challenging as it requires very specific materials in order for overlapping textures to display SSS.
So here is a Dragon as previously requested, feel free to do the SSS light effect. I used this model as if you do an Internet search on subsurface scattering you will find this particular one most used (think of it as the Barcelona chair of SSS)
