How to Enable PBR Lighting Reflections

Utilizing Built-In PBR Mapping

Default HD 64x comes packaged with PBR (Physically Based Rendering) mapping. This allows compatible shader pipelines to render realistic surface reflections and material lighting touches directly across block surfaces.

Setting Up Shaders for Reflections

1. Ensure you launch Minecraft with a shader-compatible tool like Iris or OptiFine.

2. Press Esc and navigate to Options... > Video Settings... > Shader Packs....

3. Select a shader pack that offers PBR surface lighting support.

4. Open the shader pack's internal configuration menu (often found under Shader Pack Options).

5. Locate the surface, material, or texture settings and confirm that PBR / normal mapping is enabled.

6. Click Done to apply your changes.

Inspecting Surface Reflections

Return to your world and inspect surfaces under varying light conditions. Head to underground caves to view mineral ores and stone surfaces, or observe shoreline sand blocks and water under daylight. The PBR data will interact with your shader to display realistic light reflections while preserving the classic vanilla feel.
