Baking Procedural Geometry Nodes to WebGL-Ready PBR Materials
Step-by-step workflow for converting non-destructive Geometry Nodes setups and procedural Cycles shaders into compact, real-time PBR texture sets.
Procedural shaders and Geometry Nodes systems offer infinite flexibility inside Blender, but real-time engines like Three.js or Unreal Engine cannot evaluate procedural math nodes on the fly. Baking attributes to UV maps bridges this gap.
1. Transferring Node Attributes to UV Coordinates
Store custom vertex colors, curvature, and edge wearing attributes calculated inside Geometry Nodes as explicit named attributes before applying a seamless Smart UV Project layout.
2. Automated PBR Map Baking in Cycles
Bake Base Color, Roughness, Metallic, and OpenGL/DirectX Normal maps simultaneously using high-to-low cage projection to capture detailed procedural displacement without inflating polygon counts.
3. Exporting Lightweight GLTF Maps for WebGL
Combine AO, Roughness, and Metallic textures into a single packed ORM map (Red: AO, Green: Roughness, Blue: Metallic) to drastically minimize network requests in web applications.
