The trouble with the Rogue One clip is that it’s facing the wrong way. There is an ILM clip that passes through the fleet which is incredible but it was only a low render. Why design all those ships if you’re not gonna add some awesome cinematic shots to show them off?
Could it just be mirrored? The Ghost is a pretty symmetrical ship. Or do you mean it’s facing backwards?
I haven’t seen the ILM clip. Sounds frustratingly cool, though.
