Lumen RTX Shaders FAQ

Activating the resource pack in your settings only loads the textures, not the ray tracing engine itself. You must also go into your Minecraft video settings and toggle the Ray Tracing option on, or press the in-game ray tracing hotkey while inside a world.

The toggle will remain locked if you haven't activated the pack in your Global Resources before joining a world, or if your hardware does not support hardware-accelerated ray tracing. You need a compatible RTX or RX series graphics card on a Windows PC to unlock the setting.

Activate both the main Lumen RTX pack and your chosen addon in your resource pack settings, then move the addon so it sits directly above the main Lumen RTX pack in the active list. Placing the addon on top ensures its specific textures override the base pack.

Yes, you can stack multiple addons together as long as they modify different textures, such as combining water, ore, and foliage addons. Just make sure all of the addons are placed higher in the load order than the main Lumen RTX pack.

They are two names for the exact same resource pack. Depending on which release you are using, it may appear in your resource pack list under either name, and all of the official addons will work with it.

It keeps the classic vanilla style rather than replacing blocks with photorealistic images, while adjusting the base textures for a cleaner look. The main visual upgrade comes from adding physically based rendering (PBR) for depth, varied surface roughness, and custom fog.

You need to enable either the Pink Leaves Addon or the Orange Birch Leaves Addon alongside the main pack. Load your preferred leaf addon above the base Lumen RTX pack in your active resource list to apply the color change.

If you only see the edited vanilla textures without any metallic reflections or surface depth, the PBR data isn't being rendered. Make sure another standard resource pack isn't sitting above Lumen RTX in your load order, and confirm that Ray Tracing is actively turned on in your video settings.

Ray tracing is very demanding, so the quickest way to boost performance is to lower your Ray Tracing Render Distance in the video settings. You should also turn on upscaling in the Minecraft video menu if your graphics card supports it.

While the pack can be loaded on other Bedrock devices, the actual ray tracing lighting, reflections, and PBR textures will only function on a Windows PC with a dedicated ray tracing graphics card. On unsupported devices, you will only see the minor vanilla texture adjustments.
