Thousands of thin boxes are laid out on a 45 by 80 grid and given a highly metallic, reflective standard material. Every frame each panel is re-oriented from its own position, so bands of them counter-rotate and catch the moving directional light at different angles; a soft-shadow pass and a bloom effect from @react-three/postprocessing turn the specular hits into the glare that reads as god rays down the tunnel.
