I have Carrara which i purchased as an upgrade for Ray Dream Studio from Metacreations (Remember them) years ago I like the interface and I see Carrara Studio 3 for under $100.00 and am wondering if it is worth the cost. I have Truespace 6.6 and i know Carrara #4 is available but i dont want to spend that much on an upgrade yet. Any feedback on Carrara 3 is appreciated.
