Enabling Lumen RTX Shaders and Ray Tracing in Bedrock Edition

Once you have imported the Lumen RTX (also known as Prizma Pack) resource pack into Minecraft Bedrock Edition on Windows, you must activate both the pack and the game's built-in Ray Tracing setting to see the Physically Based Rendering (PBR) textures and custom fog.

Activating the Resource Pack

1. From the main menu, open Settings and scroll down to Global Resources (or open the settings of a specific world and select Resource Packs).

2. Open the My Packs tab and select Lumen RTX.

3. Click Activate to move it into the Active list.

4. Exit the menu to allow the game to reload its textures.

Turning On Ray Tracing

Lumen RTX requires a Ray Tracing capable graphics card (such as an Nvidia RTX or AMD RX series card) and at least 8GB of system RAM to function.

1. Load into your world and open the pause menu.

2. Go to Settings and select Video from the left sidebar.

3. Scroll down to the toggles at the bottom of the Video menu and switch on Ray Tracing (or press the semicolon ; key on your keyboard while playing).

4. Once enabled, you will immediately notice the adjusted vanilla textures, balanced surface convexity, diverse material roughness, and the pack's custom atmospheric fog.
