Easy Catalog is a Blender add-on designed to automate the process of generating preview sheets from folders of OBJ files. It batch processes source files, rendering transparent PNG thumbnails for each object and compiling them into organized grid sheets. The tool is suited for managing large libraries of 3D models, where manual scene setup and individual rendering would be impractical.

The add-on provides a straightforward workflow requiring users to select an input directory containing OBJ files and an output destination. It can optionally rename the original source files to match the generated alphanumeric grid labels without altering the geometry data. Alongside the image outputs, the tool generates metadata manifest files to accompany the visual catalogs.
