I'm working on a couple of scenes right now in Carrara. One is a futuristic laptop model done in Rhino, very detailed, keys, ports etc...... The other is a car I'm working on, The wheels and tires alone were huge, the redraw time was slwed down dramatically. But so far it hasn't crashed. I'd say it is handling these better than RDS handled big stuff. Inthe end My car will probobly be over 100MB in size, it's already at about 60 MB. Time will tell.
