Ray Portal Baking Setup uses Geometry Nodes to project a mesh into its UV space, allowing multiple texture passes to be rendered simultaneously instead of relying on Blender's default baking system. By placing an object into a designated collection, the setup automatically projects the geometry. The inclusion of the Ray Portal node provides an instant viewport preview of the resulting bake.

The system supports combined, color, metallic, roughness, normal, emission, and alpha passes. To function correctly, AOVs must be attached to the Principled BSDF node of each material, as some data cannot be retrieved automatically. A provided script automates the process of attaching the necessary Base Color, Metallic, and Roughness AOVs.
