Ok, so you see major technical challenges involved in making Daz content work in Poser. That seems a reasonable theory, not that I know the details involved. It seems a reasonable theory because generally speaking the 3D industry as a whole has largely failed to establish reliable data transfer standards (unlike the 2D photo and video industry).

Is it your impression that most users are content to make still photos and aren't really interested in animation? If that's true, that would help to explain why so many people seem happy with Daz even though it's animation features don't come close to Poser, imho. So Poser has this big advantage in animation, but most people don't want to animate?

Could you perhaps further educate me about the generation 4 models? Is content for these models usable in both Daz and Poser? If yes, how does one identify such content in the content stores? Is there a list of such models somewhere that I need to memorize?
