I have given here the others parameters for the metal of the escalator, the material for the steps, the rubber for the ramp and the material for the arrival part. I increased the subdivision of the metal of the escalator to reduce the noise of the material. You can see that I've also improved this parameter in the rendering parameters.

Lighting
For the render I used the V-Ray rendering engine. In order to obtain the atmosphere that I wanted, I made about a dozen tests with different views and lighting setups to get the image that I had imagined.
I placed just two "vraylights” in this scene. There is one white light at the top of the escalator; I put the multiplier of this light at 12 in order to have a big light (I improved the lighting in post-production but I'll explain this later in the Making Of!).

The other light was placed behind the camera so that I could have a source of lighting at the bottom, and to also see some detailed parts of the escalator. The multiplier of this light was set to 2 and I gave it a blue light.
I made the lights at the bottom just with a "Vraylight” material (multiplier at 4).
The environment of the scene is a grey colour (Grey: 100).
