It amazes me how many companies have been involved with Carrara.  Lets see, first it was Ray Dream Studio and Metacreations owned it, then Eovia and now Daz.  I think there was another one also back in the RDS days.  I am just starting to try and learn Hexagon.  I normally don't have the patience for vertex modelers and just use the spline modeler in C5Pro, but I figure I might as well spend some time and learn it so I can do some more intricate designs.
