Be sure that you have the real path followed. then check the requirement some works badly on DAZ 4.9 and works better in 4.8. Try to add it manually by opening the archive. Also have a look in the readme.

Especially because V8 fully use G3 cloths and hair.

I also see that when I use multiple directory, for some character it must be in the folder "my library" and not in another place mapped to the database.

That's the point, g3 will be cheaper and G2 still a very good one and has plenty of stuff and good skins.

If you love Victoria 4 it's easy to find some at low price. So V8 is just the new toy, not for you, and V7 is now cheaper and very common.

I have tried the G8 and the V8, so far the poses of parts like hands for V3 works fine but basic poses for G3 is not working at all, mainly problems with arms.

The skins of any G3f that I have tested so far works fine on the V8 body, same for the eyes. Most of the props works fine, you sometime need you to parent the object. The autofit works well. The shaping is a need to buy with.

I have tried V4 stuff but they don't work correctly. The expression of V3 works well but not all. Male or female that I have tested are fine. I did not really see a shorter render. I may need more test.

I have tested to add the g3 genitals, with a small shaping it works. My deviant art gallery
