The more I use Carrara the less I like it. If you'r used to useing keyboard shortcuts in RDS this will be a source of frustration, you have to mouse-about to use the zoom in most windows. Also, don't plan on doing any QTVR/IVRM panoramas either. Both Infini-D & RDS had that but no more. I also think the window layouts are much more flexible in RDS. You can have several model boxes open at the same time and still maintain several univers boxes concurently from different views (if you have a large monitor). Don't get me wrong, CAR is a decent app, it's just more like RDS3D VS RDS Full version. I just don't think it's worth paying full price for. Don't forget, MC is not marketing this app as the next version of RDS or Infini-D so you wouldn't expect it to have the same features, right? Perhaps I'll change my mind after using it more, it did take about a year to really get the swing of things in RDS (I'm either slow or don't use it all that much, take you pick).
