Just got it; wonderfulness. My 5min+/frame renders went down to >1min/frame. I have a G4 876 OSX 10.2 w/8?? RAM. I have been able to bring it to its knees w/ lot's of hires objects. Closing the program and restarting between scenes seems to help so there might still be something being retained (like the txt files in P PRO.) The ability to retain my P4 libraries in their original location is a huge bonus for me. The methodology is ill explained and I had to resort to trickery (renaming) in order to get it to recognize all of the libraries.
