Biouminescent belts or some other form of light alongside the buildings would be really cool so there isn't blank spaces between parts of the factory
(or the option to use either/or if people prefer the dark spots)

Also unsure if the drills are supposed to also have lights too, but it would be nice to see those light up as well

A lot of the items being produced glow, so the idea was you can see those moving on the belts.

The drills are supposed to be lit up, but it looks a bit strange as they're rendered differently...

I'll see if I can make it look a lil better.
