Thank You!
Do you have anymore information on your IBL cheat?
What was inthe render that you lacking and had to come up with your own method.
Did messiah lack something or just frustrating to pull it out. How would you animate using your cheat? Rotoscope?
Here is an update.
I used a blurred HDRI image map. HDR prefilter ON with HDR intensity at 0.4. No Bounce Light GI, MC 6, depth 1 and GI Nosie reduction at Photons 500000, radius 100, count 400. Took about 30 seconds to render. I like the result better as it is less waxy than the previous PS blured indirect illumination layer.
Julez, the IBL cheat idea I was referring too comes from this article.

I didn’t follow the whole approach, but what I did with the HDRI was to get my indirect illumination from the HDRI environment map.

Hey Julez,
I don’t think it really is a matter of what the renderer is lacking, it is just the nature of the beast. Here is another shot with some color correction on the indirect illumination layer. Using a compositor to make these changes over re-rendering saves alot of time. By rendering the indirect illumination layer separately I have greater control over matching it to a live-action sequence or just improving the lighting without having to re-render sequences over again.
Cheers,
I am curious in your HDRI pass because you choice of hdriimage or even your cheat before had a great “flesh” look to it. Its nice and warm. I am wondering what you would od different if say you had a sky and beach hdri map. You don’t have a flat “texture pass” but your model looks like skin. The AON cell look pass contributing?
hey tony…i remember your c4d sla tests on this character…and its good to see a slightly different approach in messiah. i like the end result…seems a little specular/shiney in parts…some areas you really nail it stomach and neck i quite like…i like some of the luminous feel to some of them makes it more convincing for me at least…i think you vein layer really does the trick at first i thought it was a little over the top but when you see it in conjunction with the other layers it helps to flatter the image.
good work bud as always…keep messing.:buttrock:
Hey Tjync.
I would suggest the following for you ambient occlusion pass… Set it to linear burn at 15%, create a copy of that layer, set it to multiply at 90%-95% or something… Now go to curves for the multiply layer, and for the R channel set the blackpoint to 128, and for the green channel the black point can be 64 so it get a nicer brownish tone… This way you dont end up with the “grey/black” shadows that usually is obvious with just a regular multiply. I atleast find it much better looking.

Peter,
Thanks for the suggestion. The grayish issue was bugging me as it doesn’t look right in an outdoor setting, but fine for indoors.
Cheers,
Another update, higher-res version than the last ones.
Changes:
I am pretty happy were this is going, need a texture map, some eye balls and teeth and we are almost in business.
Cheers,
I used the St Peter’s probe HDRI map, but I think you could use any HDRI map and still get the same quality of “warmth” illumination. If I went with a sky, I would add a slight blue on the occulsion pass or create an ambient pass with a slight blue and multiple it with the occulsion pass. For the beach HDRI I would use it in my indirect illumination pass. If you know of a good beach HDRI map, I would like to try it out with this series of test.
Cheers,
Here is what I got from the beach hdri. It was abit overcast, so I raised the brightness a little bit.
Cheers,
I thought I’d keep things tidy by posting my skin studies here with Tony’s. And it’s also a way of bumping up his very informative thread. Julian posted a Maya SSS shader here which prompted me to investigate the subject matter using Taron’s Basic Shader. This is the Butch character with a little more sweat applied, this is a straight render, no post work:
From what I have been able to play with the Basic Shader is better than the Maya plugin and is very robust for all kinds of SSS skin creations. You can also mix SSS effects by applying more than one Basic Shader to a Final Radiance node to get some very interesting skin effects like the creature Gary posted on the other post. For example one SSS can be used for the inner sub-dermal skin with Extend-Shade or whatever and another SSS is blended in for the outer dermal skin with Extend Color. You could also use weight spots to define areas like the ear with a SSS to get the redish-vein shading, freckling and so on. Doing SSS skin shading with messiah I have found compare to others, C4D, XSI and Maya far simplier, better and faster.
Cheers,
One thing that the Basic shader doesn’t do, that the built-in native translucency does, is show light falloff within the object. The whole object is lit uniformly whether the light has fall off or not. I’ve brought that up to Taron’s attention. But, it can be faked to a certain degree using meta-effectors. See Julian’s tutorial. It would be great if messiah had weight maps to define areas of translucency as well.
Gary,
Faking can be accomplished in post, but have you tried blending a translucency standard material with a Basic Shader+SSS custom shader material to see what would happen?
Cheers,
