Enable PBR Surface Details on Your Terrain

Understanding PBR in VoxelVibranceShader

VoxelVibranceShader uses noise-based PBR (Physically Based Rendering) to add surface depth and texture variation to blocks without changing their shape. This creates the illusion of roughness, wear, and material variety while preserving Minecraft's blocky aesthetic.

How to See PBR Effects

1. Load a world with VoxelVibranceShader active in OptiFine settings

2. Look at stone, dirt, and ore blocks up close—you'll notice subtle surface detail patterns

3. Move around to different lighting angles; PBR details become more visible under varied light conditions

4. Compare lit and shadowed surfaces; the noise-based texture responds to light direction

Maximizing Visual Impact

• Build in varied terrain with multiple block types to see PBR differences between materials
• Use natural lighting (sunlight and shadows) rather than flat artificial light to highlight surface details
• Explore caves and underground areas where shadow contrast makes PBR depth most apparent
• The effect is subtle by design—it enhances rather than replaces the classic blocky look

PBR details render automatically; no configuration is needed beyond having the shader active.
