Thanks to both, but nope. Given time zone, I actually had switched off the computer completely last night (having only the select tool selected), went to bed, just started computer and daz again without changing any tool, loaded the character, same thing.
I even loaded with merge (so, not replacing, but in parallel) another character, and there is no problem there, as you can see. Again, it is not a different scene, it is a different character, loaded in the same scene, so, even the rendering parameters are the same.

About the switching on and off the tool, as I wrote, I anyway had not only made sure I did not have any "special" tool active, but switched off and restarted completely the computer, with no change.

At the same time, I use often mesh grabber, less surface editor and more rarely joint editor, and never had the need to restart Daz, disabling the tool by switching to another one is always sufficient to go back to the normal/correct visualisation - maybe is a matter of version, but never had that problem.
Which makes even sense, e.g. I used mesh grabber to make some modifications to "advanced pussy" and to a nose for a character and save them as a morphs, but I had to do various incremental steps getting the morphs back in mesh grabber, then modify, save it, see if I liked it, etc. if I had had every time to restart Daz, it would have been a mess, it is not the creation of a full character, but it is a kind of creative workflow.

What I did have in the past was forgetting that DAZ remembers the last tool active, so closed daz, then opened it, saw something strange, and realising only after it was not because the character was someone damaged, but it was because I still had mesh grabber active - but it is not the problem this time.

Anybody knows if there is any surface setting that may create that colour problem ? Honestly I think it is probably more a problem of some setting about surfaces and that is why it appears only when using Iray (neither filament nor cartoon textured have the problem, but I use Iray for rendering, don't like the filament images and are visibly different, so not an alternative for rendering).

Edit : I tried changing the "transmitted color in the genitals", and I got what seems a small improvement, at least the colour is less strong, but the problem is still there

The problem with trying to answer something like this is there's so many different things that can cause that kind of overlap, and it's real difficult to predict without loading the scene myself. When you turn off all geoshells, did you verify the shader on the gens object is identical to the shader on the torso region?

also in extremely RARE cases I've seen gen grafts not be able to copy over certain torso shader properties, usually stuff like dual lobe settings and you gotta set them by hand.

If you can just remove the parts of the figure you dont want shared like specific morphs, then you could upload the scene subset and we could easily take a look at it and figure what's wrong.
