Subsurface Base Shader Usage

I did a bit of testing with the Subsurface Base Shader.  I wanted to try this out with Genesis and a Gen4 UV.  The following was used:

Subject: Renee for Genesis which uses V4 UVs
Lights: UberEnvrionment2 with KHPark, Intensity 80%, 4XHi and YRot -65

The second image was rendered without changes to the default Renee surface parameters.

The first image was rendered after applying the Subsurface Base Shader to groups 1, 2, 3 only.  Shader not applied to eyes. No edits.

The third image was rendered after setting the the Ambient Color and Strength to the original Renee defaults, the Pre SSS-Post SSS to 1, Group ID settings to 1,2,3 respectively, and Subsurface Off - On to 1.  No other edits. Shader not applied to eyes.

In the renders using the Subsurface Base Shader there are artifacts in the eyes (edges) and especially in the mouth area where one can now see the teeth.  I tried several different combinations but was not able to improve upon the third image.

I went through the write-up supplied with the shader but do not see what I am missing.  Anyone have any suggestions?

**** FIXED ****
By applying scorpio64dragon’s catch of my oversight in the next post.  The fourth image is the corrected one.  It would be handy to know if there are other optimizations that could improve this so if anyone wishes to comment, that may help us to understand how best to apply the shader in this type of scenario.

My bad.  Missed that in the doc.  That fixed it.  Thanks.

The result is pretty good but there are likely optimizations that would improve it so if anyone has other suggestions…

Put a fairly strong spotlight behind pointing towards the camera, then apply the tricks we learned from Poser characters and users: reduce diffuse colour to a very light blue, and set SSS colour to fairly strong red. You’ll have to experiment as to the relative colours, the ideal being that if you have only direct lights the skin result looks like skin, i.e. neither too red nor too blue.
It’s looking good, by the way!

I did a couple of Renders with the Subsurface Toon Shaders in the new 4.6. I just used the straight render settings with no adjustments to see what they would look like. The Eyebrows are done with the Genesis Eyebrow set. I was pretty impressed with how they came out versus trying to do toons the old way. I included an example of a toon style render done the old way and one done with the New SSS Toon Shaders so you can see the difference.

Reading the documentation seemed to indicate that there are pre-sets for the Subsurface Shader somewhere but I can not find them.
Any help would be appreciated.

with a basic shader presets are not installed they should be purchased separately

but if you carefully read the documentation will be able to do without them
shader is easy to set up

The presets are in the store you have to buy them,
http://www.daz3d.com/new-releases/subsurface-toon-shaders
http://www.daz3d.com/new-releases/subsurface-gummy-plastic-shaders

unfortunately the base doesn’t come with any presets.

Thanks.  Don’t know if the two can really be de-coupled, but in the first pass I was trying to keep the lighting at its simplest and focus on the shader settings.  Will try again with this and perhaps a canned light setup that everyone can access (e.g. Wancow’s at http://www.sharecg.com/v/69039/browse/21/DAZ-Studio/WC-3Delight-Baseline-Test-Lighting).

Your renders look good but
I’m not finding them easy at all to be honest I find PW and Ubersurface2 a lot easier to work with as well, I haven’t got one decent result using this shader yet, render times are increased massively, got one now going its stuck reading the information been doing it for 10 minutes using Uber2 the render would have finished by now.

Very nice, Slide3D! I know it’s your Francesca character (she’s cute!), but please share which lights/lighting you used in DAZ 4.6? I think it’‘s the most realistic character render I’ve seen yet with AoA’s new shader. And do you have a render time noted?

2 distand light for rim(50%) and fill(20%) with raytreced shadows(Shadow Softness 30% for rim and 5% for fill light) plus UE2 in Bounce Light(GI) mode
render time ~20min (i7 2600K)

I’m not sure I fully understand this, and I want to. Lighting in 3Delight is the bane of my existence. Lighting in Lux and Blender could not be simpler but 3Delight is still an absolute crap shoot for me. Are you using default lights or is this some kind of trickery buried in the bowels of my runtime?
Gorgeous rendering btw.
