Well, I just can't pass by a good Carrara rant when I see one, and this one has generated a good deal of response, even though Milaja was asking an innocent enough question which Willf's response should help with. I'm afraid I share most of Tephladon's opinions about Carrara and I'm on a Mac. I've been supporting, repairing, upgrading and creating with Macs for over 15 years and am quite familiar with problem software and hardware that the Mac faces. The constant Type 2 & Type 3 errors are all coding issues in Carrara. I've been a faithful user of Metacreations/then-Fractal Design products for 8 years; the reason being they always worked and I NEVER had a problem with them - especially RDS (sorry Clint). RDS chugged along since version 1 without a hitch no matter how complex a scene I created, except for over-taxing the amount of installed memory. I expected the same from Carrara and have been very disappointed. I've learned a few workarounds to keep it going, but that isn't what I paid for and isn't how I need to spend my Oh-So-Scarce creative free time. I'm using RDS more and more again because it does the things I want it to without complaining and crashing my machines. I wish I could discover exactly what the problem is but it is so different in everyone's experience. I support two other designers who use Carrara and 1 has no problems and the other has threatened to quit if they have to use it. Since there are two of us with the problems, we're looking into other software. I'll keep experimenting with Carrara and what it can and can't do, but most of my work is getting done in RDS until Carrara is fixed or I find a killer new program or RDS won't funtion any more.
