This is what has given V4 this unnaturally long life as the primary poser figure. and she will not be abandoned my most until the arrival of a universally accepted and superior POSER NATIVE female..perhaps project E?? time will tell.

At least for me V4 and M4 are a good mixture between speed and quality. I have played around with the DSON import, but honestly I haven't had any good experience with it. Most the times i have to restart Poser because it gets screwed up due to it also I find most the characters to be slow to work with, which quickly annoys me, I like the characters and all, but I think its to much problems getting it to work correctly with Poser and having read the guide on Daz3D on DSON didn't help anything, I personally don't think these figures are worth the trouble for the images i make and as someone already mentioned if you need a high resolution human mesh, you can do that by simply go Figure -> Skinning method -> Poser Unimesh and just increase the subdivision level.

So a mixture of people having a lot of content for V4, but also I think a lot of people have problems with the genesis characters (especially the new ones) when using poser and personally i think its sad that the users are caught up in this "battle" between Poser and Daz3d that it have a negative impact on the experience that they have using these programs.
