I went to RIpple Training and downloaded the classic generators missing from my version of FCP 10.8. They are sitting on my desktop in a folder with 12 subfolders of the generators. How do I get these classic generators I downloaded from Ripple Training into the Generator Browser of my FCPX 10.8?
Go to your Movies>Motion Templates>Generators and drop the RT Classic Generators folder into Generators. If you don't have a Motion Templates folder or Generators folder create them in finder in Movies folder. The path should be ~/Movies/Motion Templates/Generators/RT Classic Generators. That should allow them to show up in FCP's generator brouser.
