A simple fun test I did, running displacement on a few elements using an image I generated with Midjourney.
The scene has one plane and two cubes.
A few lights, a volumetric cube (so that makes 3 cubes, sorry ^^), a camera move and a Mixamo character later, I now have a gloomy scene with some weird looking blob enemies roaming around.
There's probably a hidden artefact somewhere close.
