On the crawl issue, this may be of some interest…
Jackpumpkinhead’s Custom Crawl Creator: Revisited (A Free Blender Project for Fan Editors) thread
with a few other similarly useful / helpful threads that are listed in the An Index Thread for Star Wars Fan Edits and Other Projects… and also the An Index Thread (and more) for Star Wars Preservations…
Good luck with the project mate 😃
