Wow! John that shader looks pretty amazing, though slightly inflated around the nostrils. I’ve heard good things about the fry renderer. Can you expand more on your render, approach and light setup?

Fry’s one of those unbiased renderers right? i think this could be a big step forward in the next few years as an alternative to MR. Maxwell is producing some amazing stuff, cant wait to see how people use the new rewritten SSS shader.

Is the character rendered in fry too? http://www.johnstrieder.com/images/js-hommagefinalnew2.jpg or is this post?

I certainly wouldn’t aim for such a scientific approach… And most people aren’t after 100% photorealistic results anyway, the large majority actually overdo the translucency effect as it’s usually more pleasing to the eye.

I’m all for 100% photorealistic results.

[Shonner]

I think this is the closest i’ve seen so far, pretty amazing shader:

But still looks CG, can’t quite figure out why, any thoughts?

See http://www.ballisticpublishing.com/books/essence/face/dvd.php which shows how this is done. The amount of CG look in the results is up to the artist.

PS using max.

I have that book…

This is what you get when you hit render with the file that comes with it:

Not what I expected.

After a little work and Fry render I have this so far:

Still some work to do me thinks.

I don’t like John Strieder’s girls lips too much but I can’t get my girl to have the proper shinyness like his

[Shonner]

I didn’t get the DVD for the book because the files are never complete. They’re just for training. The book makes you do some work though to achieve great results.

Well it makes reverse engineering a little hard but I do like the book.

and this with SSS and Reflections:

The more I look at it I can see how well she is coming along. Are you still using the 6 layers like in FastSkin? Is it all in one material?

[everlite]

I have the book, however i dont want to pin myself to these techniques, i still think there’s something missing, but that said still a good book.

pluMmet: another interesting result from the fry renderer. Though some heavy blacks.

I’m wondering if using an unbiased renderer is the answer. Though from past experience with Maxwell (im sure frys similiar) you can’t tweak, test, tweat test, its more like, tweak, test and go and do the weekly shopping then come back to a grainy render still at 25% It was a while since i had that experience, is fry quick on the renders?

Thanks everlite,

Can you expand more on your render, approach and light setup?

this was a Rendertest for “Willpower”, i used this scene to tweak my Skinmaterial further.
Light is only two Emitterplanes (one from the front and one from the back).
I was inspired by the MentalRay FastSkin-Shader and made two Reflection-Layers, 2 Diffuse (different Roughness and colour here) and 3 SSS-Layers. Those Layers are working like Laa-Yosh described in his post.

Yes, I love the approach and the comfort of the unbiased Engines. The new SSS of Maxwell looks interesting. Maybe now it`s possible to create a realistic skinshader with MW, too.

All my Images are rendered in FryRender and no postwork* . This Image is a little bit older, my Skin Material is more realistic now (i hope)

*(except sometimes adding grain or colour degeneration, yet the Hairs are not a Post-Effect, they are Polygonstrands and use advantages of FryRender, like SSSSS (Single Sheet-SSS) and Thin-Film-Coating).

Maxwell’s new s.s.s. is Amazing but still flawed. It doesn’t allow for any kind of texture map.

I’m in love with Fry as whole. I also think the answer is in unbiased.

As far as testing with Fry it is faster then Maxwell. They have a sort of quick response rendering thing going on. The first 3 or 4 minutes go very fast then the normal unbiased thing sets in but it’s enough time to get an idea of how it will go.

John seems to have been harder at work at it then me. When ever I add layers to skin or when I turn the roughness down (for shineyness) the skin gets all dark like I’m mixing acrylics. I’ve been frustrated many times at it :hmm:

How are you setting up reflection layers in Fry?

@everlite: Unbiased engines are much faster now … and with a unbiased engine you have the comfort to see the whole Image immediality, unless it’s more or less noisy at the first time.

(Yes, far from perfect, it was just a test :p)
rendered about 4 Minutes in FryRender on my QX6700, i think, this is not slow.
Just keep in mind, there’s - biased-spoken - always Full GI, traced Reflections, Caustics etc.

@pluMmet: Yes, 7 Layers actually (2 Diffuse now). You could try to let your Material look like Skin before Texturing! Texturing is the next Step

I have tried that but I get the acrylic effect I just mentioned where when I add layers everything browns out…

Nice render johnstrieder !
FryRender sss looks good .

pluMmet, you’re posting way too fast - or I’m too slow

Really? Didn’t know that. Then it’s still impossible … in MW 1.8 maybe?

Creating my Material wasn’t so hard, cause I used the results of FastSkin as guide.
Specularity … hmmm … one of the Layers is Roughness 15 and ND of 1.36. 90°-Spec-Colour is light-blue. I’m using a weight-map now; before I used Textures, i think, it was a weight of ~20%. If a single Layer is relatively dark, you can exceed the 100%. Maybe in future I use Roughnessmaps.

Well you’re inspiring me to try some more that’s for sure. I’ll try these settings and see how it goes.

As far as being fast on this subject, it has my attention :lightbulb

I’m on a quest for photo realistic skin in Fry. I have her looking fairly good using Mental Ray but I want her to look like I want from within my chosen renderer.

[everlite]

Eric:

Do you have a high res version of the render you posted earlier? i’d love to see it a little bigger. What do you think are the current disadvantages with the fry setup you’re currently using? … now come on, im sure there’s a few

I’ll download the demo when i get a moment free. So the shader you have, is this one that you’ve custom built, or is it based on a existing shader with tweaks? Just wondering if its quite a tough job coming up with these kind of shaders, i remember Maxwell wasn’t for the faint hearted

Dave.

I have loads of test files saved. It would just be a matter of finding it and rendering it higher.

As far as disadvantages… John doesn’t seem to be having the trouble that I am. It seems to me that if I can understand what I’m doing wrong that he is doing right that Fry will give exactly what I’m looking for. I have to pick his brain.

The shader is built by me. Though I have about 70 variations of it

To me my girl looks good for someone with makeup on. Unfortunately I don’t want it to look like that. I can’t get the s.s.s. in Fry to be there and the specular to be there at the same time but John can…

[everlite]

Apologies man, haha i was sightly confused there, the request for the larger image was meant for John (the one with the lips) … you’re renders still cool (probably need to kiss but some more now) … Though still black in areas. Oh man did i get my wires crossed with that one. D’oh!

Dave.:argh:
