SSS, Domina, Genesis 2- HELP

Scott Livingston · March 2014

These ones use Lantios Lights 2, Preset #8.

This one is the "DTAL-ThreePointB" preset from this set: http://www.daz3d.com/advanced-light-presets-for-aoa-s-lights

Obviously, with default settings, there are some issues with the eyes, but the skin itself I think looks pretty good under this lighting.

Will you go to the surface tab and check some settings for me? Do the skin surfaces (like face) share a Group ID with the inner mouth and gums perhaps?

Yes, they do for Domina, and for V6.
More details about this: for Domina, there's one group ID for teeth, another for eyes (iris, pupil, and sclera), and a third for everything else that uses the AoA Subsurface Shader.

Domina's Group ID for skin by default is the same as V6's, so if you want to use them both in the same scene, you may need to change the Group ID of one or the other.

If every light in the scene (no matter where it is, or where it is pointing) isn't set to raytraced shadows you will get glowing mouths and glowing heads. It's because without the raytrace setting on the light will go through the back of the head/body and make the parts glow from behind. With raytracing on, those lights are blocked by the back of the head/back of the body. But without raytracing lights in DS go through everything, walls, floors, props, other characters and will find the back of the mouth/head and will make it glow. Most lighting sets contain one or more lights not set to raytracing and as a result are really poor for SSS characters.

More details about this: for Domina, there’s one group ID for teeth, another for eyes (iris, pupil, and sclera), and a third for everything else that uses the AoA Subsurface Shader.

Domina’s Group ID for skin by default is the same as V6’s, so if you want to use them both in the same scene, you may need to change the Group ID of one or the other.

Change the group ID number on the inner mouth, gums and tongue to something else. Try adding a 0 to the end of the current number so it won't be the same group as a different body part.

Unless the bodies are going to intersect then the group numbers being the same will not matter. It can't view them as a single surface (as in your skin is a surface on your body) if they are not intersected.

While your at it you may want to check the teeth.. for some crazy reason they have the reflection set at 100 percent on the Anna texture and sometimes this stuff gets carried through even when its odd.

Edit to add: Every light must have raytrace shadows on. This includes the UE lights used in the scene.

Last one for tonight...here's Domina with the Domina Lights 2 preset, with the following changes made:

- Changed Gamma to 2.20 and turned gamma correction on*
- Changed Group ID for Inner Mouth, Gums, and Tongue
- Turned on raytraced shadows on the point light
- Changed Domina's Shading Rate to 1.00 (8.00 by default)
- Changed Domina's Shading Scale for Group 61 (skin, inner mouth, etc.) to 0.1 (0.5 by default)
0.1 is physically correct for Shading Scale, but perhaps lower than you might want to go, aesthetically speaking
(Diffuse strength and subsurface strength were not changed for any surface...and probably should be, as belovedalia found)

All these renders use an overall render shading rate of 0.1

*I still use gamma 1.0, GC off as my default, but I'm starting to experiment more with changing this.

With so many changes at once, this isn't really good science--hard to say how much impact each one of the changes had--but I'm signing off for the night so I wanted to show the results of changing a few things from default values as others suggested.
