PBR Painter is a layer-based texturing addon that enables multichannel PBR material creation directly within Blender. It automates the generation of complex shader node setups, allowing users to modify albedo, roughness, displacement, normals, and emission channels simultaneously through a custom user interface. Materials can be constructed using imported texture maps, procedural generation, or a combination of both.

The tool includes features for procedural edge-wear generation, texture painting, and material segmentation using ID maps. It supports the creation of reusable smart materials that integrate with Blender's Asset Browser. Additionally, it offers automated high-to-low poly baking capabilities and is compatible with both Cycles and EEVEE render engines.
