This was the intro scene idea for the SELF Eurostars video I did. It didn’t go far because, obviously, it was rejected but mainly because I had too much to do and at some point I totally forgot about it; I like to finish even the rejected projects I already started.
Making this was quite simple, I used the already modelled tube and put it in different scenes inside of Blender with the same settings except for the environments. One I downloaded from Sketchfab, another one was done with height maps, another one with a displacement modifier, and the last one with a vanilla Blender feature. I downloaded all of the textures from the internet.
