Hey... heres a little glimpse of my sss tests in octane...

this is still Wip ... ( I definetly have to many of them ) 40% done... I need to remodel whole body ... and work on some other stuff here...

kool wip .. waiting to see the final result !! btw..I like the slogan.."swell...." hehe..good one

haha thanks 3rdeye .... Its hard to work with it... beacuase Im laughing more then working

You blended diffuse with an refractive material or mixed isolated materials for every scatter layer?

HEy lucek.... for now its mixed specular with scattering and glossy only for reflections on his face...

Now I will be preparing maps for this and making shader more complicated....

but main reason to get good SSS is the lightning.

For me the weakest point of this SSS shader is lack of the scatter radius option. I did some tests today (look at image). I tried to mix some refractive materials to fake sss layers - one of these scatters red, other yellow. Unfortunately it cannot mix properly. If only i found the way to amplify red scatter (or change scatter radius). Differing the scale factor doesn't takes effect too:( Have you tried that? Sorry in advance for leaving mess in your thread;) notify me if you want me to delete that.

I really dont understand Your setup...

please dont remove it... please even post the effect with the rendered image... so we can watch it closely.

Ive had controll over the radius... but You have to do it accordingly to scattering direction... then its working. At least for me ... or maybe we are talking about 2 different things...

For now this wip is without textures... and shading is pretty ok... I will be putting the subdermal textures in a minute... so leater Ill post what did I get with my SSS plus textures...

BTW I found absorption helping much.... ofcourse Im absorbing the blues ... so the reds are coming out.

Now I will not post the settings yet... but when I finish this with textures I can help...because for now I dont think that my SSS test is the best out here .

Yes, I know it's ok. You know, shader that scatters with red light looks ok, but providing that you render a simple meshes (like this cartoon guy in your picture). Normally I don't use octane, but if there's a sss material I need to test that feature;) My main purpose was to create layered sss shader, like that in mental ray. I would like to mix three materials, that scatters (each one in other colour).
Back scatter - strongly transmit red light (ears and shutters)
subdermal - transmit subtle brown/orange light - Overall shape of face
epidermal - transmit almost white light that blurs the face in strong light
That is the first time I try to create it in octane. You have more experience with that render, maybe you will succeed in doing that shader.

Here I post my fast layered sss test done in mental ray today. No idea how to do it in octane?
