P.S. People keep talking about how it's too bad that the DE effects weren't rendered out at motion picture resolution. Well, apparently some frames were and this one
sure doesn't hold up at high res (click on it to zoom to full res). The windows and the human/vulcan/deltan figures in particular are totally awful.
To be fair, if done now for 1080p or higher, it would be shaded much better, and the CG figures would have proper textures of the actors faces mapped to them, etc.
Their final project target was DVD resolution, and they knew it, so they took the shortcuts needed to make it good enough for the resolution.
In 480p (DVD) you really can't tell it's that bad.
