Pbr Normals

• Normal Maps Core

Purpose: “Add significant detail by modifying pixel direction” Naming: “_n” at end = normal map convention Result:

• Makes surfaces look extruded/3D
• “Creates illusion of higher detail” • Allows lower polygon meshes • “Heavily used in gaming industry”

• Combining Normals

Use “blend-angle corrected normals”

• Takes: base normal + additional normal
• Blends them correctly

• Normal Intensity Control

Process:

• Keep blue = 1 (constant)
• Use component mask (R,G only)
• Multiply R,G by intensity value
• Append blue back

Parameters:

• Base normal intensity
• Top normal intensity
• “Set default limits to prevent breaking”

• Organization

Use reroute nodes (double-click wire) Group with comments (‘C’ key) Can duplicate setups (Ctrl+C/V or Ctrl+D)
