Adjust PBR Surface Reflections for Different Block Types

Understanding PBR Material Properties

The physically-based rendering system in this shader pack calculates how light bounces off blocks based on their material properties. Metallic blocks, water, and polished stone will reflect light differently than dirt or wood.

Customizing Reflection Intensity

Access the shader settings menu (typically opened with a key combination in-game). Look for PBR or material-related options:

1. Locate the Specular or Reflectance slider

2. Increase the value to make all blocks shinier and more reflective

3. Decrease it for a more matte, natural appearance

4. Test changes in different lighting conditions—bright sunlight and caves show reflections differently

Fine-Tuning Per-Material

Some shader packs allow per-block adjustments through resource pack edits. Check if your installation includes material definition files. Metallic blocks like iron and copper should have higher reflectance values than stone or dirt.

Practical Testing

Build a small test area with various block types side-by-side. Observe how light behaves at different times of day and in shadows. Adjust settings incrementally—large changes can make the world look unrealistic.
