How to Enable Ray Tracing and PBR Textures in Bedrock

Defined PBR is a Ray Tracing resource pack for Minecraft Bedrock on Windows. Unlike standard texture replacements, it uses Physically Based Rendering (PBR) textures and heightmaps that only appear once you switch on the in-game Ray Tracing setting.

Activating the Resource Pack

1. Open Settings from the main menu or your individual world's edit screen.

2. Scroll down the left sidebar and select Global Resources (or Resource Packs inside a specific world's settings).

3. Open the My Packs tab, click Defined PBR, and press Activate.

4. Confirm it appears inside the Active drop-down list before backing out to let the game reload its assets.

Turning On Ray Tracing

1. Load into a world or stay in the main Settings menu and click the Video tab on the left.

2. Scroll down to the bottom of the video options to locate the Ray Tracing toggle.

3. Switch Ray Tracing on.

4. If the toggle is greyed out, verify that Defined PBR is active in your resource list and that your system meets the hardware requirements (a compatible Nvidia RTX or AMD RX graphics card).

Once enabled, blocks will immediately render with depth-mapped heightmaps and uniform material properties, while built-in fixes automatically resolve vanilla RTX rendering bugs on entities like the player, villagers, horses, and the Warden.
