Carrara was once one of the best mid-range 3D applications.  There was a time it seemed if Daz was in a position to make it the best of all of their programs; a viable alternative to Poser with modeling and landscaping built in.  Somewhere along the way it became almost an afterthought.  Unlike Daz Studio which, despite being forever in beta, improved greatly in a few years, most all improvements to Carrara (while also forever in beta) seemed to revolve around catching up to D|S.  Carrara users waited ages for paid upgrades which ignored long standing complaints and instead were foisted half-baked Genesis compatibility and content management which from the sounds of things seems almost universally despised.  There's still a good program in there, but it should have been a great program by now given the amount of work the community has put into chasing and documenting its bugs - many of which would never have been introduced had Daz simply improved the areas that needed attention rather than shoehorning the bits and pieces of Studio the geniuses at Daz figured Carrara needed to fit in with their content-centric business model.

In their defense, there's no way they could continue developing Carrara and not include Genesis compatibility.  There are many Poser users who still can't accept that Poser isn't and never will again be ideal for using Daz figures.
