Hey Hal, hope you’re doing well.
I decided to give removing the Wookiee noises from that problematic scene a go:
As you can see, I had an issue with when the clone spoke, since Chewie was groaning over his entire line. I solved this by giving him a new line from the 2004 Battlefront. (Voiced by Temuera Morrison of course!)
PM me if you would like the audio file.
Edit:
Still not 100% happy with it, will tweak further! 😉
