I think the problem with DazStudio was that it was plugged or seen as a Poser killer and it just isnt.
What they should have done and still could do is concentrate on what it should be.
Daz3d sell 3d content and DS could have been a great little entry level figure posing and rendering app. If it was just that they could concentrate on getting it working properly and leaving the heavy lifting to the likes of Bryce and Carrerra.

Unfortunetly they have taken aim at their foot and let off both barrels!
