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.
SNW cheats by using a digital set for their alien worlds instead of Planet Hell. Just change the objects in the foreground and swap out the images on the screens behind the actors and you have a new planet. This set is also used for Engineering, with some railings and consoles installed.
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.
