Caption has most detail. But here’s more on the ideas I had making this.
I origionally planned holes in the middle of the railings in a pattern right after another but knowing it would take a lot of time and already have made divisions in the middle to start with them I put the middle poly’s inward so the cross pattern would be like an I-beam
I also wanted to put in glass tubes for the elevator cars to go in and would’ve done it but it made the image look crowded and you couldn’t see the platform good.
I once had the idea for slits coming out of the cars to attatch to the metal cylinders but that was clunky and didn’t look good so I went with the halos like origionally planned. I knew I would need env. maps to make them show in reflections but the way it turned out without them I found they weren’t really needed in how the camera was set up.
I also had the idea that the fake window lights made with a texture affecting the emit value would go across the embossed cylindricular wall lining in a vertical fashion but horizontal just ended up looking nicer.
And I avoided myself from having to make entrances in the wall by positioning and scaling the wall so there would be no visible spot where it intersected the paths.
