The color is customizable, this was what I went for from one of my reference images. In fact all of the colors are customizable for these props, just like everything else I’ve produced. =)
The pipes use at minimum 20 edges. Though I am considering adding more divisions on the skinny wall pipe variant where it curves, in order to improve the silhouette.
It was brighter originally, but I ended up fading it a bit just so it doesn’t stick out too much.
I’m using Quixel Suite 2.0. Very interested in giving Substance a try sometime in the future though. =)
