I fund it. part of confusion is that the resource URL in this site for several versions all point to same page on Renderotica site.
I tried another version from ZGFX and that had the rest of the assets.
But it's not a very good prop as it is not just limited to G8 it is also limited to only one character as the textures don't match anything else. Even then it displays a white triangle where pubes would be located. There is even discussion with the developer on this who two years ago promised upgrades...but never appeared.
For the gens itself the realism is good but it's actual usability is very limited.
Try it...but I personally don't think it's even worth the effort.

What is a good alternative for a texture source that would work with G3M that is better than the basic DAZ assets? Ideas?
