I didn ' t realize it was a command line program , I thought it was like the gdx setup program . As it turns out , someone made a gui version of it linktexturepackergui . Thanks for the help though ! <| sep |> I used FCPX for one job once for a few months and it isn ' t a bad program , it ' s actually quite powerful , it ' s interface is just so radically different that it ' s like learning editing from the ground up . Maybe newer editors would appreciate it , but I started out cutting on film so I appreciate that FCP 7 is designed to be like cutting film , as is Avid and Premiere . FCP 7 is definitely still used more in professional settings though , and I know my school still has it and never upgraded to 10 . <| sep |> Is there anything special about the two places it broke ? Was that just the place with the most impurities ?
