Renderotica

I know I asked this once before, but it never seemed to get resolved...

The problem is that even though I  choose a brown anus, plus the skin around the anus to be brown, on most models it comes out either grey-ish or white-ish. There is no difference in any of the anus color settings.

Here is Victoria 8.1 with choosing the darkest brown anus settings when setting up the gens for her...

If you alter any of these parameters on just the gens geo-graft you will get a mismatch with the rest of the figure but it can be fixed with a little work in any 2D image editor that supports layers. Using a mask layer you can apply a colourise filter to darken just that area of the Diffuse > Reflection > Base Colour image for the New Gens Anus surface.
Once you have the mask sorted you can save as a template for easy application to the mat images of other figures with the same issue.

You could also create a mask to apply to the offending parameter if you know which one / ones are to blame but just darkening that area of the Diffuse colour image should do the trick.

It is difficult for the mat copy script to cater for all possible material types when there are so many different ways skin mats are done in Iray bet perhaps a greater range of anus colours to choose from would come in handy?

So the thing is though, I'm finding maybe 2 or 3 total characters out of several hundred GF8 characters have anything resembling brown anuses, and even they aren't consistent if the light changes. The rest are white, or light grey. Certainly nothing I'd call dark, or brown. Even if you cover them with the pubic hair, it's like someone's shining a flashlight through the hairs back at you. And, there is no difference in what you choose. If I choose light, flesh or dark brown, it's all the same. Most of the time I don't bother and just use the regular gens because both the anus and the surrounding area can easily be colored any color you like, including brown, and all that without fiddling with any editors outside of Daz. What I miss though, is that the "wet" feature is not usable with the regular gens. So it's like we have this wonderful "wet" feature for one version, and a useable anus colorization that is easy to use for the other, but neither one incorporates these two features in one program. It's "take one, but not both" kind of thing. Very unsatisfying ...

Here is a snippet of taking a real anus and applying onto the color map, which can be done with any simple paint program.

But that doesn't look real at all. It's bright red. The texture is real enough, but it looks like it's been pasted onto the gens, and not actually integrated. It looks very odd and out of place. Have you ever modified the colors for the regular Newgens for GF8? You do it all in Daz under "surfaces" where you simply choose which one to work on, and you can change both the core and surrounding colors to magnificent "realistic'ish" effect. I'll see if I can find an example and post it...
