Just be aware that currently there's some confusion over why Transposer 2 wasn't included with Carrara 6 Pro and without it you can't import Dynamic Clothing or hair and many PZ3 files into Carrara 6 Pro that were created using Poser 7. Hopefully they'll be fixing the updates for folks who have previously purchased Transposer 2 with Carrara 5 or 5 Pro so they don't have to pay the extra $100 or $40 for PC members additional costs for Transposer 2 for C6!

Also, there seems to be an issue with Carrara 6's ability to search mutiple runtimes for calls from one figure and textures and OBJ's are having to be manually located by many people. If you have external runtimes, it has been found that if you have the word "Runtime" anywhere in your runtime folder structure above the actual runtime itself that Carrara has even more difficulty in locating items. 

IE:
Good folder Structure:
G:Poser ContentDAZ ContentRuntime
Bad folder structure:
G:Poser RuntimesDAZ RuntimeRuntime < Two Too many uses of the word Runtime!!

As with any new software release, the users are finding all these issues that should have been caught in Beta Testing phase and filling the forums with posts about them. 

Reccommendation: 
Wait for the kinks to be found if you don't need the stress of testing software.
