Been a hot minute, but if you’re new here, this was a type of (literal) test-bench scene I was doing back in the Early Access phase of Unreal Engine 5 a few years ago – mostly with the aim of testing out the different new features that UE5 had to offer and then later on, figuring out what had changed or which bugs had been fixed which each new version of the engine.
So this one was rendered in Unreal Engine 5.4.2 on a 3090 using Nanite for most meshes, Lumen for GI and reflections and a combination of Megascans, Blender modelled & textured assets, and third-party assets.
(also now with fish!)
