Bryce was primarily developed outside of Daz 3D with the first version released in 2001 for Macintosh. Ironically Bryce no longer works with the new Apple OS systems.

The Bryce content management systems is definitely easier to navigate but having a simpler split of content allows for this more straight forward system. eg Only needing one category Objects for any mesh object.

When you look at the History of Daz as a company you can see they were originally formed as a creative group making content for Poser. Which is why the two Applications have a lot in common.

The first version of Daz Studio was released in 2005 whereas Poser first poked its head up way back in 1997. And gave a lot of direction to the development of Daz Studio.

Even more Ironically in 1998 Poser and Bryce were both owned by Metacreations. Bryce then passed through Corels hands to finally end up with Daz 3D in 2004.

Poser has also passed through a number of hands such as curious labs before ending up with Smith Micro.

Its amazing how much this little family of Applications have developed over the years. And unfortunately its never as simple as it seems. :D
