I've had RDS5 for some time now, I've been studying the manual and working on learning to make the most of what it has to offer. I'm thinking of upgrading to Carrara when version 2 comes out in the fall. I'm having second thoughts about waiting to upgrade, because after I put the time into learning RDS5, I don't know how well what I've learned will carry over to Carrara. If I learn RDS first, will the knowledge carry over to Carrara easily, or will I have to pretty much start from square one with Carrara? If that's the case, I'd rather not invest so much time in learning RDS5 and just upgrade now. Any suggestions?
