Koam, Rhino is real nice software but. Carrara needs to improve its interferes for advanced modeling users. I kinda get tired of limitations in it. I rather not to play around with Rhino because I am not up to learn other softwares. ZBrush is awesome just like Rhino but it was pain in the ass to re-learn its own curves. My wish list for Carrara is improve symmeterical and movement coordination with mouse on polygons like Zbrush.
