Well, all this tests have been done with the models I've created for my next scene for the apocalypse contest. I won't talk here much about that scene and I'll open a proper thread whenever I get it more advanced. But for now I just wanted to test out the materials. The scene was built with two premises, first one not to be an archviz scene (I've already submited one) and the second one, to use the new features of Octane, SSS and the incoming instances.
All this examples are work in progress both in modeling and texturing. They've all been rendered in PT for under 2 minutes with an HDRI as light source. I've added a test material render with fake SSS done mixing specular and difuse, or as in the tree just difuse with translucency. You can clearly see that the SSS does not only look much, much better but its quite faster, in the girl from 3.33 with SSS to 2.30 with "my mix", and in the tree same happend and it was against a difusse material! WOW
Also the tree might look "nicer" the diffuse one but that's because the tree is seen from under the foilage looking at the sun, so the correct and expected result is the SSS one not the diffuse one. The skin needs a map to control the scattering (the nose seems to fade) and they all need some tweaking but keeping in acount that I've used an "out of the box" specular it looks great, so does the dress, with a subtle transparency.
Well hope you like it and make tons of new awesome renders with SSS!!!! have fun!

- All the materials in the scene have SSS they all look better than my attempt at fake SSS
-
-
- I looks ok but it has no depth, it's cold
-
- I looks just as it should even thou my leaves distribution needs to be fix, this is a test to try to build a tree with instances (leaves, branches) so I can create many more for my scene
-
-
- it looks good, but it should look like this when seen from under the branches
-
-
- there is some geometry errors that I'll have to fix, althou they are planned to be view at medium long distance, but you never know

in specular material how did you do to give more color to the leaves?
You can do this thanks at software you use to model or i be able to do the same with a Rhino?
maybe my english(google traslate) is not good!!
Multicolor is possible because your modeler software allow it or you do this effect whit octane??
maybe you can share the material in livedb??Please
Thanks a lot

you mean the tree leaves? well there is 4 different leaves instanced in a single textured and aplied to 4 diferent meshes with their uvmaps adjusted so they'll only show one single leaf. I'll share it once I get the material right, now it looks okay but not quite there, but if you need it in a hurry send me a pm and I'll send it to you. You can do this with any software, there is nothing software specific, actually I started this tree following the guidelines of a tutorial for trees for blender and I don't use blender (yet), I did it in max, but it could be achieved in any soft.
http://scotchtapeworm3d.wordpress.com/2 ... poly-tree/ I took my own approach and used instances for everything, but is a great guideline
The original texture from the leaves is from cgtextures, modifying 4 different ones and doing a 2x2 array with them.

I cant figure out how to get Wax/SSS for a candle. It just does not scatter enough i guess.

I've tried a quick fog with no success, I'm intrigued by what Radiance said, but I haven't had much time, I'll try tomorrow and see how it can be achieved, besides I'm quite interested too cause I was planning on using something alike for my scene.
PS about the candle watch out the scale it has a HUGE importance in SSS. The ones I didn't have the correct scale couldn't get a good result, I'll give it a try later too

You are right on the spot. I even use the scale parameter to boost the result. Now i have a proper wax material in my thread Thanks.

small update, I've got the other character's face ready and decided to give it a got at the material, this time is a diffuse material with SSS and in this case I've got all the textures more or less ready. Again, as the rest, all done from scratch manually. Hope you like it.

well a couple more tests with my characters, still a lot of work to do, but SSS is looking so good I can stop "testing". The sunglasses are a specular with SSS for the rim. I think this will we the last tests of this scene here, I'll open a proper thread for the scene when I get to do some more "scenery".
Hope you guys like it.

I'm still working on the SSS effect, small tests using a plane as emmitter for a more dramatic effect, for him I've used a rgb colour for transmission and for her a map. He was rendered this time in PMC for about 5 min and her in PT for another 5
