Thank you. The saber duel was one instance of shot-by-shot correction (or creative LUT mixing and application), since what was good for the red saber was bad for the blue. Took a while to do and to refine.
The reason I included the continuity fix for the Cloud City window was because the error was introduced by a Special Edition change. So, while I don’t know which Piett change you’re talking about, I’m not really concerned unless it’s a problem the SE(s) introduces.
