Dawn sins were many:

• too few morphs and not designed to be used as building blocks (like DAZ morph packs)
• the default textures unusable to create freebies
• very difficult to morph in programs like Blender
• very slow release of specific content.

If these easily predictable errors had not existed, Dawn might have taken off.

Hivewire3D had their occasion and they squandered it; I see no other realistic option for a post V4 Poser native mainstream figure. Unless a mad idea of mine: SM is badly integrating/castrating Cyles; what if they tried to do the same with MakeHuman? they could sell it to the point-and-clickers as Poser "Genesis".
