G2M Anatomical Elements Surface in iRAY?

So....I searched for G2M surface or something of the sort, after 8 pages of G3M crap, I gave up...
How does one actually apply IRAY the G2M genitals? I have several tools to convert G2* figures nicely, but none seem to understand the genetals (I haven't tried the females...)
I tried copying the Figure's Hip surface and pasted over the genital's hip and genetalia, but that left some pretty scary dark patches on the scrotum and other places...not to mention the fact that the hip region still glowed like a chinese lantern. WTF? How does one get those parts to look right? Why don't these shader tools we purchase not work properly with the "nether parts"? I assume G3M's privates render nicely, but I haven't tried

This is the way I do it, but it's far from perfect.
Select the gen with the surface selection tool and note where the maps are. Select the main character's hip and save it to the content library as a shader preset. Apply this saved shader to the gens, then go to where the gen textures are and change the base colour, normals, specular, displacement etc. back to the gen ones. You will need to test render and tweak it untill the match is close.
If you save the hip material as a Mat Preset isn't there an option to apply the surfaces preset without the textures? Those "scary dark patches" are probably because the hip texture image is being applied to the gens.
same issue with G2fem here
I belive V3's Iray Tools support Anatomical Elements. At least the G3 Version does.
If you save the Hip surface as a Shader preset and hold the Ctrl(PC)/Cmd(Mac) button while double clicking on the shader preset you will get a pop-up that allows applying the shader without changing the current textures on the surface.
1). Load your character, with all appropriate textures (some characters come with a different hip texture for use with genitals).
2). On the surface tab, select all of the character's surfaces.
3). Using Ctrl-Click, apply the Iray Uber shader to the character.
4). Deselect the character, then load the Genitals, with the matching textures.
5). Repeat step 3 for the genitals.
6). Save a material and/or shader preset for the gens.
7). Use 'Fit To' to apply the gens to the character.
OK, so I tried again, and I'm getting closer, but it's still a total fail!
Here is what I did (G2M here)
Loaded the character and applied the regular 3delight textures.
Converted regular character via the G2 V3D converter (v3d digitimes shader script)
Altered the translucency color and reflectance tint until I was happy (I was going for a nice, rich tan, and am very happy with the results)
Saved that as a material present.
Save the hip as a shader preset
Loaded genitals and applied the 3delight shader
Applied the hip shader preset and held Cmd+click to avoid applying textures
And this is what I am seeing. The genitals are GLOWING! Any suggestions about this? I really hate to devolve back to "Base Color Effect: Scatter" if I can avoid it. But, I suspect the genitals are misbehaving due to that feature. The values on both the genital/hip and genital/genitals match the values on the character's hips, aside from the textures.
I'm not sure what the rules are for posting men's junk...so, I am posting just the very top portion...hopefully that is clea and doesn't offend anyone's sensibilities:)
Something else to look at:
If you applied the Iray Uber shader (as nightwolf1982 advised), when you go into the Surfaces editor (Editor tab on the Surfaces pane) and scroll down, you will notice a number of parameters that weren't there before.
Take a look at the Emission parameters (color and strength). If your surface is 'glowing' as you describe, it might be because those values are out of whack; try dialing them back a bit....
What confuses me is that these are exactly the same settings as I used for the skin. I didn't directly use the DAZ3D shader, but I used one of the commercial G2 Iray shaders here in the store and modified the translucency settings to look nice and tan...but on the genitals, those same settings....well, they don't look so good..as you can see:)
The V3D can be used on Anatomical Elements by using the Geograft icon & the script then copies the setting automatically
I tested this and it appears to work for me but I do not usually render these parts so my idea of OK may not be yours :)
Mambanegra, first your image is going to get removed as it is not in line with the forum's rules on nudity. Second, are you sure the gens are using the same shader as the skin? The shader name is located at the top in the Surface pane.
Meh. If they determine that it's against the rules, then I guess this topic doesn't belong here at all, sine it's difficult to help someone with even a hint of a render of the problematic area. And yeah, I was using the same shader. I suspect that the "mesh density" (no clue what to really call it) is too shallow and the transmit gets way overblown because the simulated effect things it's an ear or the edge of skin and doesn't realize that it's physically attached the much thicker complete figure.
Anyway, it works just fine if I turn off Scatter + transmit in the translucency settings...I just wanted those settings because the character looked better with them on...oh well. Even with just scatter, the match isn't 100%, but it's not super noticeable. I guess this design doesn't work as well in IRAY as it did in 3Delight. I wonder if the same problem exists with G3Ms genitals? I haven't tried that, so I don't know...
It could be that turning down translucency to a much lower number would work. I may play around later to see.
EUREKA!
Doh! I can be such an idiot! I was using the same shader...but, I hadn't thought to set the underlying texture like the script had done for the rest of the translucency settings. So, when you compare this one with the skin, they did look the same because the numbers and colors were all the same, but those underlying textures weren't identical:/
It's till not 100% perfect, but it's good enough for my needs.
Hopefully, this will be helpful for other folks later on.
Check that thin-walled isn't on in the surfaces setting for the anatomical details. Sometimes they seem to default to thin walled and that may cause that glowing effect.
