Full ray tracing is a demanding but highly accurate way to render light and its effect on a scene. Also known as Path Tracing, this advanced ray tracing technique is used by visual effects artists to create film and TV graphics that are indistinguishable from reality, but until the arrival of GeForce RTX GPUs with RT Cores, and the AI-powered acceleration of NVIDIA DLSS, full ray tracing in real-time video games was impossible.
In Black Myth: Wukong, full ray tracing increases the fidelity and quality of lighting, reflections and shadows. Reflections on water reflect all surrounding detail. Water caustics add further realism, accurately rendering the refraction and reflection of light. Particles are reflected, making battles more dynamic and exciting. Fully ray-traced lighting ensures lighting indoors and outdoors is pixel perfect, darkening areas where light is occluded or doesn’t reach, and realistically illuminating the world by bouncing light. And in concert with the lighting system, contact hardening and softening fully ray-traced shadows are cast everywhere, rendering the smallest of shadows from leaves and pebbles, and those from geometry-rich buildings, the main character, and the gigantic bosses that must be overcome.
Full Resolution Multi-Bounce Ray-Traced Indirect Lighting
With multi-bounce ray-traced indirect lighting, natural colored lighting bounces up to two times throughout the world of Black Myth: Wukong, creating more realistic indirect lighting and occlusion. Rendering techniques including Screen Space Reflections, Screen Space Ambient Occlusion, and the existing GI solutions were replaced by a single, unified algorithm that delivers more accurate lighting of scenes and objects, making each scene as immersive as possible.
