To be completely honest with all of you... I really don't see that much of an improvement on this new genesis model.
Sure, the expressions got overall better than the previous model, but as of now there's literally no reason as to why someone would even want to switch on that if not, like someone else already said, for a bit more of photorealism and such - which honestly, It's not even that much unless rendered in high subD as always, and for example I can't benefit of that since with my current rig rendering as high res is not an option. So it's just another model, for me at least.
I've done some tests myself with both g8.1 base and vic as well. And also the g8 with the pbr shader. While it indeed looks good to the eye, on the other hand at least for me there are quite a few problems and the most important of all is the fact that I can't use the face control because of the morphs I have. Mind you, I don't have 285619 morphs installed because recently I even purged
most of them, freeing also space, but most likely if I had a clean installation of daz with only the base genesis and the newest, the program certainly wouldn't crash on me everytime I try to use it. Because that checks all of the possible morphs installed and.. well..
kaboom. So the only thing I can use, are the dials that come with it and that's it.
Another thing for me that doesn't work are, even tho I mentioned before the pros, the expressions: both with g8.1 and vic as well they feel.. all the same. They dials all the same and there's literally no variety. And as always, smile at 100% it's "freaky" as hell.
Then there's the obvious, for now, problem about most of the meipe and similar assets which doesn't work as of now (at least not properly and only with manual configurations), but luckily GP as well as other three assets received already some "fix" to be accepted from the new genesis model.
But still... I don't see any reason, again, as to why I should switch to the newest genesis. Or even someone else. And I don't understand why most of the daz users are screaming like is some sort of "miracle" that they released this g8.1. Just for the enhanced expressions?
