Img2PBR is an add-on and shader node collection designed to generate physically based rendering (PBR) materials from standard flat images directly within the Shader Editor. The tool set includes nodes to process source images by removing baked-in shadows and specular highlights to create cleaner base color maps.

The system outputs standard PBR maps, including base color, metallic, specular, roughness, emission, normal, alpha, ambient occlusion, and displacement. It also features utility nodes for colorizing black-and-white images, adjusting hue, blending colors, and posterizing generated materials. In addition to image-based material generation, the package includes procedural texture nodes that do not rely on external image files. The tool supports both the EEVEE and Cycles render engines.
