Bedrock RTX: Double-click .mcpack to import → Settings → Global Resources → Activate → Enable Ray Tracing in world

Step 4 of 5

4. Activate the pack

Step 1 — Global activation:

Open Minecraft and go to Settings → Global Resources. Find Optimum Realism in the list and click Activate. This applies the pack to all worlds by default.

Step 2 — Enable ray tracing:

Create a new world (or edit an existing one). Go to the world settings and look for the Ray Tracing toggle — turn it ON.

The first time you enter an RTX world, it may take a minute to load while the game compiles ray tracing shaders. This is normal.

Common Mistake

Ray tracing only works in worlds that have it enabled. You need to toggle it ON in each world’s settings — it’s not a global option.
