waterfall forest 3d model

Prompt: "An open-world, hyper-realistic ancient natural sanctuary environment created for Unreal Engine 5.1 using Lumen and Nanite. The scene features a colossal, moss-covered waterfall cascading into a crystal-clear river. The river bed has intricately detailed PBR (Physically Based Rendering) textures for pebbles, submerged logs, and realistic underwater caustic lighting. The dense forest is composed of photogrammetry-scanned broadleaf trees, ancient ferns, and dynamic ground cover that reacts to wind. Wildlife includes a highly detailed stag with procedural fur, several species of birds with unique flight AI pathing, and schools of realistic fish. Lighting is a dynamic time-of-day system, showcasing beautiful volumetric fog and god-rays at sunrise. Everything must be high-poly yet optimized for realtime rendering, featuring 8K seamless textures and micro-vertex displacement."
