Noding a PBR 3D model means connecting its texture maps (albedo, metallic, roughness, normal) to the matching inputs of a PBR shader node in a node-based editor (like Blender’s Principled BSDF or Substance Painter’s Node Graph).
This links map data to shader properties—albedo for base color, roughness for surface smoothness, metallic for reflectivity—to simulate realistic material behavior. Common steps: Import your maps, add a PBR shader, and assign each map to its dedicated input (e.g., normal map to the shader’s normal slot).
Beginners should start with the software’s pre-built PBR templates and tweak one connection at a time to see how it affects the model’s appearance.
