Hey, here’s a video from a guy who makes very interesting videos about how CG was done in movies:

It’s in French but there are English subs.
I really like what he does, he always interviews people involved in creating the effects he’s talking about! And there’s also a video about the Special Edition trilogy on his channel (in which he might talk about the CG trench effect) :3
Awesome video, even at the 3rd time of watching! I’ve always felt the VFX work for ROTJ, especially on the DSII, never quite gets the love it deserves.
Even stories about the building of the DSII are few and far between, and find it a little disappointing we haven’t seen more of that on screen, even in any of the animated series.
