Quick Baker is an add-on that expands Blender's native baking capabilities to handle multiple objects and maps simultaneously. It streamlines the creation of PBR textures and mask maps, featuring a high-to-low-poly workflow with an automatic cage setup. The tool includes support for UDIM baking, channel packing, and baking material IDs from vertex colors. It also provides map previews and node-level baking options. The add-on requires materials to be built using only the Principled BSDF, Mix Shader, or Add Shader nodes.
