I have to admit there was a time when even I was asking for Genesis support in Poser, mostly because I was too eager and wasn't thinking clearly. All I needed was to read SMS's official answer, where they have explained that it would be impossible both technically and legally. They have also called attention to how odd it would be for SMS to have to replicate every single thing DAZ ever did to their software. We don't think much of it, but DAZ has a disclaimer where they are free to change anything at any time without notice. Many times I have found myself unable to locate a feature from the DS interface because it has been changed, removed, renamed, or moved to another part of the interface. And consider all these changes on DS are not even documented. Imagine if SMS would have to update Poser every time this happened to maintain compatibility with the Genesis platform? Can you imagine Poser devs running after DAZ to know what has changed that is breaking Poser compatibility with Genesis? That would be crazy, and yet, that's what people were (and still are) expecting Poser devs to do.
But the craziness doesn't end there - different versions of Genesis only work in specific sub-versions of DS 4. Each of these different Genesis versions depends on specific DS 4 versions to work, and are incompatible with all previous versions and sub-versions. Nonetheless, people expect ANY of them to work in Poser, even if this doesn't happen in DS where they are at home. There is so much people are taking for granted. I don't recall this exactly, but I think [from the back of my head] that Genesis 3 requires at least DS 4.5, and Genesis 8 will not work in any version of DS lower than 4.10. And how was Poser supposed to seamlessly handle all that when all of the Genesis platform is closed, undocumented, and proprietary?
I didn't realize any of this when I first started asking for Genesis support in Poser. I was just thinking of it as a "figure", not realizing that it's a platform. And most of all, it's also intellectual property of DAZ, who I assume wouldn't be just giving it away, even less to their competitor (?!), just from the goodness of their hearts. That wouldn't even make sense. They are rival companies. Why would DAZ ever do that? I can't imagine how this would ever work out. There is so much people are taking for granted when simply asking Genesis to be supported in Poser. The amount of reasons why this can't happen is so vast that it's just crazy.
