Is Skin Builder 3 the only option for building skins (in Daz)?

When you do all these custom morphs and shaping, the other half of the equation is the skin.

Looking for a way to generate/edit/adjust skins.

This looks like the only one-in-all solution in town

From the feature set, this looks like the right answer - blend skins, add blemishes, adjust pores, veins- looks like it does is all.

Problems and Questions

1) It only says Genesis 3 female and I don't see the male equivalent- so is this unisex, by all accounts?

2) Is there something else that makes skins, aside from the 106 products to do small parts like add blemishes or adjust SS or shine or wet looks or geo-shell this and that- or even dumping the textures in photoshop and making edits, etc......

3) Is a shader system a viable alternative? There's quite a few products that do skins with shaders, but I'm looking at the small physical details like a mole or freckles etc...products like anagenesis https://www.daz3d.com/n-g-s-anagenessis-for-genesis-3 ; use this approach, but I'm looking to make distinct skins and not so much a general tone that blankets the whole character.

4) I don't see any threads dedicated to this product- with like, examples of use or any threads with problems or troubleshooting.

How easy is it to use? And really save and store your presets?

And back to the main, does this work on males?
