OneClick PBR Library is a material asset collection and complementary add-on for generating PBR materials in Blender. It allows users to convert folders of PBR textures into ready-to-use material assets in multiple resolutions. The generation tool handles downscaling, creating 2K and 1K versions from 4K sources, or 1K versions from 2K sources.

The included asset library contains over 3,000 PBR materials compiled from popular CC0 texture websites. These materials are pre-configured for the Blender Asset Browser, supporting drag-and-drop workflows. The collection includes a wide variety of surface types such as asphalt, wood, concrete, fabric, and metal, provided as .blend files categorized by resolution.
