Volumetric/SSS rendering playground

Okay had to do the buddha :)

Damn this SSS is super fast.

looks transparent?.. is this volumemtl?

[Javadevil]

Yep just playing with the SSS distance and G.

Another one without transparency

Are you sure? I think, i can still see through it ;]

[maru]

I think it needs IOR>1.

[Ondra]

the best way to make it completely not see-through is to use translucency instead of refraction

[Javadevil]

Theres no refraction, its set to 1.0.

[lacilaci]

Theres no refraction, its set to 1.0.

you mean that IOR is set to 1.0 but you are using refractivity instead of translucency, right?.. You should set refractivity to 0 and instead play with translucency, absorbtion and sss color to get proper sss media behaior i think...

[Javadevil]

Right I'll try that,
I thought the transparency was coming from the marble texture in the SSS slot.

not bad :) thanx Ondra and team!

Haha the sss looks very nice ! when can we expect to try it? i've some characters who sure would love to have a corona sss treatment :D

    I am messing with the tests, and discovering things here... I could not get rit of the transparency on the edges sometimes (as bellow), but i was playing with Refraction/IOR and tranlucency,etc...

    I will try to not use Refraction anymore to have opaque edges... Take a closer look at this, and the edges on the yellow shader are transparent. :(

     And i am still suspicious about Reflection/Spec lights absorption/scatering.

Ok like Ondra said i've picked the wrong color in Absrp, now it's good :D

Did you use refraction or translucency? But there is definitely something wrong with this. If there is a bright area (like area light or some highlights) behind and object with SSS material, the object becomes transparent or there is a lot of noise going on. But I think that's why there is a huge text informing you it's in an early stage of development. :)

Nice results Chakib ! The Juice looks awesome.

    But take a look at the Straw, it's stills sharp even inside the fog. That's what's confusing me about this SSS workflow....
 
     On a Dirt Water/Juice, or something like that, the rays are messed and sort blurred in real life, but inside a FOG or smoke the rays aren't messed too much, so the objects with sharp edges inside the volume looks ok, but it i miss the refraction of thoses rays... Maybe using Refraction Glossness is the way to make it looks right ?
