{{Q|Ray tracing for Windows brings a brand new experience to Minecraft! Experience creator-built worlds with realistic lighting, vibrant colors, naturally reflective water and emissive textures that light up.|[[Minecraft:minecraft.net]]|Ray Tracing}}
'''Ray Traced'''<ref group="fn">Refers to the graphics mode in the game.</ref> or '''RTX'''<ref group="fn">Primarily used by {{w|Nvidia}} in their promotion and marketing for the [[Minecraft:w:Nvidia RTX|RTX graphic card]].</ref> is a [[Minecraft:graphics]] mode that improves the visual fidelity in ''[[Minecraft:Minecraft]]'' with {{w|physically based rendering}} and real-time lighting simulation using [[Minecraft:w:Ray tracing (graphics)|ray tracing]]. It enhances graphics of sunlight and moonlight with light rays, adds [[Minecraft:water]] effects, reflections on all blocks, and light-emissive textures. It can be enabled using client-side [[Minecraft:resource pack]]s that define PBR texture sets. ''Minecraft'' has published several RTX-compatible worlds for free in the [[Minecraft:Marketplace]], in collaboration with Nvidia.

Ray tracing only affects the graphical appearance of ''Minecraft'' and has no effect on gameplay. However, many emissive light sources and reflections together can decrease game performance, especially on lower-end devices.

== Features ==
[[File:RTX default light sources.png|thumb|The default light sources and their colors. Notice the diagonal shadows caused by ambient occlusion.]]
By default, [[Minecraft:torch]]es, [[Minecraft:redstone torch]]es, [[Minecraft:lantern]]s, [[Minecraft:soul lantern]]s, and [[Minecraft:end rod]]s are strong emissive light sources, which create dynamic shadows using ambient occlusion and illuminate surrounding surfaces with their light color.
[[File:RTX VV emissive textures.png|thumb|All blocks that have emissive textures from Vibrant Visuals, as seen with ray tracing.]]
When a ray traced resource pack without PBR textures is applied to a world, not as a [[Minecraft:Settings#Global Resources|global resource]], it applies all MERS block textures for [[Minecraft:Vibrant Visuals]] and ignores subsurface scattering. Metallic, rough, or emissive pixels are generally less intense than in designed ray tracing resource packs, but still noticable with the effects from ray tracing.

=== Physically based rendering ===

=== Directional lighting and shadows ===

==== Volumetric fog ====
{{For|customization|Fog definition}}
[[File:RTX pale garden fog.png|thumb|The strong fog and light scattering in [[pale gardens]]]]
Ray tracing supports [[Minecraft:volumetric fog]], an additional fog layer which is affected by directional lighting, and can be customized per [[Minecraft:biome]]. Depending on the density, volumetric fog appears around directional lighting; the stronger the light the stronger the fog. The density can change with the [[Minecraft:altitude]] and fog is not applied above the build height limit. Media coefficients change the scattering and absorption of RGB light when it passes through [[Minecraft:Sky|air]], [[Minecraft:clouds]], or [[Minecraft:water]], to tint the fog and directional lighting.

Fog can be applied to the sky, the sky during [[Minecraft:precipitation]], [[Minecraft:water]], [[Minecraft:lava]], and lava with [[Minecraft:Fire Resistance]]. It is only visible with directional lighting, both sunlight and emissive textures. As light shines between objects, the shaded air does not have fog and the illuminated air does have fog, resulting in light rays. Light rays are also created by scattering from the sun, which has different colors and strengths depending on the [[Minecraft:time of day]].

When enabling ray tracing without custom fog settings, it defaults to the biome settings defined for [[Minecraft:Vibrant Visuals]].

=== Water effects ===
[[File:RTX water.png|alt=Ray tracing|thumb|Water in ''Minecraft'' with ray tracing]]The [[Minecraft:water]] surface is completely transparent with [[Minecraft:RTX]], but larger bodies of water accumulate more [[Minecraft:biome]]-colored fog. Although it is transparent, water can still have PBR textures allowing for reflections, but this is disabled by default. Light sources can illuminate the surface and the fog below the water with their color, and once sunlight hits an underwater surface, animated caustics appear.

Water surfaces also refract light from objects on the other side, but unlike refractions from transparent blocks, this is a slight distortion effect that bends objects behind it around the point of view. The top surface as seen from underwater projects [[Minecraft:w:Snell's window|Snell's window]], a bright lens around which objects on the other side are distorted. The underwater surface always acts like a perfect mirror for close underwater objects, as such the environment above water is not visible inside shallow bodies.

Without directional lighting, underwater fog creates a dark green/blue atmosphere with all objects colored gray.<gallery widths="200">

== Applying ==
Ray tracing requires a [[Minecraft:resource pack]] with <code>raytraced</code> capability in its <code>[[Minecraft:manifest.json]]</code> file. When applied on a compatible device, this unlocks the "Ray Traced" option in the graphics mode dropdown in the [[Minecraft:Settings#Video|video settings]]. It runs locally on the player's device, meaning that it can be enabled on any [[Minecraft:multiplayer]] world or [[Minecraft:server]] while other players could have it disabled. The resource pack may be enabled locally as a global resource pack, or for the entire world or server.

Ray tracing cannot be enabled in the regular settings but requires the "Allow In-Game Graphics Mode Switching" option to be enabled, to enable ray tracing in-game. It can also be enabled by setting <code>graphics_mode</code> to 3 in [[Minecraft:options.txt]].

Some options related to ray tracing can be adjusted in the "Ray Traced Graphics Options" section below the graphics mode, which includes upscaling for GeForce RTX graphics cards with NVIDIA DLSS 2.0. Upscaling makes the game render the scene at lower resolution and upscaled to the native resolution to improve significantly on video performance.

The render distance for ray tracing is controlled by the "Ray Tracing Render Distance" slider instead of the regular render distance slider. This slider can be set between 8-24 chunks, but can be changed to any value chunks in options.txt.

=== System requirements ===
The ray tracing graphics mode is only available on the Windows version of {{BE}}, with additional minimum requirements:<ref>{{cite|url=https://help.minecraft.net/hc/en-us/articles/4408865164173-Minecraft-with-Ray-Tracing-and-Advanced-Graphics-FAQ|title=Minimum Requirements for Ray Tracing in Minecraft: Bedrock Edition for Windows|website=Minecraft Help Center}}</ref>
