Next thing you're gonna tell me they often reused a cave set or ran the same footage of a Klingon Bird of Prey explosion
The TNG shot is from the inside of a Dyson sphere somewhere in the Alpha Quadrant, whereas the VOY shot is from the inside of a Starfleet R&D hanger on Earth.
I'm trying (and failing) to find an image, but I want to say they re-reused it again in ENT when they entered one of the spheres in the Delphic Expanse.
Edit: Nevermind. I was thinking of TNG: Relics after all.
