In the SE and 04 version when Lando takes Han and Co to the banquet hall to meet Vader, there's a big bay window in the first shot walking toward the room and it vanishes in all subsequent shots.
I've completed the effects to add the window into all but one of the shots and I just can't get the last one to look right.
It's the wide angle shot where the stormtroopers first file in, I just can't seem to get it to look right.
Seeing as painting things into frame seems a bit more up your alley than mine, maybe you would be able to add the window to that last shot. I could email you the rest of the shots if you wanted, to save you the work on them.
If not, oh well, the error has come to George's attention and they're fixing it for the next release, anyway.
