In the beginning there was an empty space illuminated in the center with white light (you can see this in the first post of this project).
Then I decided to add objects of different heights so that the difference in height was noticeable. The pillars are randomly placed, it seemed to me a good idea. Well, then texturing.
Such a dark environment is related to the plot, most likely you already understand why.
P. S. Forgive me for my English, I'm bad with that, I use a translator.
