Volumetric/SSS rendering playground

[vkiuru]

I haven't had my morning coffee yet and am still a bit fuzzy, maybe this has been answered before but can this be used to simulate long distance aerial fog with a box or a gizmo? What would be great.

yes

Hi!!
My test SSS.

[juang3d]

Just a bunch of random renders using the new volumetric rendering ;)

Regarding this first post and the cluod pictures, can this material be applied to a particle simulation so we can achieve a similar look to what the old afterburn plugin was able to achieve?

Cheers.

yes

But it doesn't work if camera is inside this box/gizmo, right?

[Ondra]

it will when you set that material also as the global volume material ;)

ooooooooohhhh shiiiiit

Congrats Corona Team for Volumetric/SSS shader
Waiting for the next build to try.

[vkiuru]

yes

Personally this is a very, very wanted feature and I need to try it out as soon as I get done with my current job/project.

little test.. for understand how interact all parameters i need more test but.... i love it :D

[racoonart]

I don't know why but this actually looks tasty :D Maybe it's a bit too much jelly-bean-ish

hahaha maybe because when I was doing this test I was hungry :D
you are right.. its a speedy test for start understand how sss works.
I must understand all interaction between translucency refraction and the new parameters of sss... :)

Don't get me wrong, I really like the shader ;) Maybe not what you had in mind but I'd keep it :D
Yes, it also took me quite some time to get a feeling for it.. the mix of translucency, refraction, absorption and SSS gives unexpected results at first, but it helps if you try to follow the ray shot at the object in your head and imagine how it is modified by the different parameters.

  Now, that we have more and more artists getting their hands on SSS Build, don´t you guys feels that FrontScattering and "spec/Reflection" Absorption still looks strange ? I know that´s a Work in Progress code/implementation, but i had this feeling and can´t see no one complaining about it. So i am starting to wonder if it´s something real or just my imagination...

     Testing side by side with Vray SSS2, i can feel the incredible BackScattering effect MUCH more than the fron Scattering. I had to make Blend Materials or tricks to get the specular/reflections to look smoother and better, but in Vray it still looks a bit better on this specific point, the specs has some feeling of absorbtion embed, like the front light gettin into the surface and spreading (I guess this is called front scattering, right) ? Maybe it´s a case of "G" Adjustment. Vray have the default Phase (Aka G, on Corona), not set as ZERO like on Corona. But i don´t know if its a direct relation of those numbers...

thanks for your suggestions, I really appreciate, I'll try to think like you said.
