Render for Catalog handles batch rendering in Blender when you have many objects that each need the same lighting and framing, such as images for catalogs, thumbnails, or icons. All objects must be present in the project, either directly or as links to objects and collections from other .blend files.
The workflow starts by choosing one object as a reference and setting its framing and lighting. You add a reference cube, resize and position it around the test object, then add your objects to the addon's list. A "Center objects on reference" button positions and resizes every listed object to fit inside the cube, aligning them for the chosen framing and lighting. Cameras, lights, and set objects each go into their own lists, and you set the render names before launching.
Multiple cameras let you capture different views of the same object. A selective view can hide all objects except the highlighted one or drive visibility by list index, and selective rendering re-renders only the checked objects. The render format and path follow the project settings.
