This is my first finished project in Unreal Engine (UE5EA), or any game engine.
After many years of using only e-on's Vue for my images, I had to try Unreal Engine. Some months ago I saw Epic's demo project featuring Lumen and I knew then I had to try Lumen at a cave environment. I saw a bunch of tutorials online and after some failed attempts, this is my half-decent image. Lumen didn't disappoint. This image (and the video) are produced using exclusively Lumen, no ray tracing is involved here, or postwork. UE5 is really fantastic, I'm really impressed.
