A scene based on a real place down in South Wales where my grandmother used to live.
Deep in the country there was a spring that bubbled up from within a dark cave. Across the stream that it produced were a bunch of large fallen trees we all used to run across to get to the other side.
Made in Unreal Engine 5, with a mixture of render outputs and settings. Some pathtracing and some real time. Really good fun putting these scenes together.
