Hey there @suppehue1! So if we’re talking about the emissive pattern on the walls and such, I think they are just kind of panning around a noise texture and lerping or multiplying for the emission. I didn’t have a good noise texture on hand for this on hand so I used the start content water as a map. it’s depending on whatever noise texture you use and you can even have a sine to lighten or darken it. I used contrast for this one but I turned it off to show this off.
This is plugged into the emissive
For this result:
It would definitely need more processing past the texture portion to get the exact look, but this will settle as a base to get started! Hope this helps!
