How to Enable PBR Highlights and Depth with Compatible Shaders

Default HD 256x includes built-in PBR (Physically Based Rendering) mapping. To see surface depth and realistic material highlights, you must pair the pack with a compatible shader pipeline.

Enabling Shaders in Video Settings

1. Ensure you are running a shader-compatible environment (such as Iris or OptiFine).

2. Open Options... > Video Settings... > Shader Packs....

3. Select a shader pack that supports PBR materials and labPBR standards.

4. Open your shader pack's internal configuration settings if available, and ensure PBR or Normal/Specular Mapping is toggled on.

5. Click Apply or Done to save changes.

Verifying Surface Highlights In-Game

Return to your world and locate an area with varied light sources:

• Examine Underground Rocks and Ores: Place a torch near exposed ore blocks or underground rock formations. Look at the blocks at an angle to see subtle light reflections and physical depth along the texture ridges.
• Inspect Brick and Wood: Move around building structures featuring brick and wood surfaces in direct daylight. The PBR mapping generates realistic surface highlights as the sun moves across the sky, adding visual depth without altering the familiar block shapes.
