To move from 3d one needs 2d art, not 2d shit.
2d here is really bad from what i have seen.
p.s. but thanks for 75 hint.
If you meant you want all the old 3DCG art back, that simply isn't possible as they no longer exist in the game files, they get completely replaced as the 2D art gets made.
If you want those scenes back you'll have to overwrite them yourself using the old image files. I shared a link in this forum a while back to a zip file containing all the old 3D art, search some and you'll find it.
And no I don't have the link handy anymore, nor do I plan to find it again. I happen to dislike 3D Custom Girl a lot so I don't wanna put any work in it, I've already done my part by making the assets available.
Though keep in mind, this won't contain 3D artfor newer scenes, as those images flat out isn't being made.
Also I get you don't like the 2D art, which is fair art is subjective, but calling it shit just because you don't like it isn't gonna change it, no need to be juvenile about it.
