rocky waterfall 3d model

A vibrant, flowing and realistic 3D model of a waterfall and river system. The riverbed and the area where the waterfall lands should be covered with sparsely distributed, wet, smooth grey stones and rocks. The water surface must include white foam and ripples to convey fast flow and waterfall splash effects. The water color should be a bright, slightly turquoise and clear blue. The model should be optimized for game engines (e.g., Unity/Unreal Engine), preferably a low-poly to medium-poly mesh. Generate with high-resolution PBR textures (Albedo/Base Color, Normal, Roughness, AO maps).
