Aged and neglected ancient cathedral with crumbling stone walls, a stunning stained glass window glowing faintly as fragments, fractured by time, hang suspended in the air. Sunlight from above pierces through a jagged opening, casting radiant god rays that illuminate the swirling dust. Tiny, sharp shards of glass float amidst the light beams, creating a mesmerizing dance of colors and shadows. The scene bursts to life with advanced raytracing and rtx rendering, producing intricate reflections and vibrant detail. Unreal Engine and Octane elevate the spectacle to breathtaking realism, showcasing finely tuned 4k and 8k textures, enhanced by captivating volumetric lighting that brings every element into vivid focus.
