Mass Export is an add-on that automates the process of saving multiple objects and collections into separate files. It supports 3D formats including FBX, OBJ, GLTF, and native BLEND files, alongside image and video formats like JPG, PNG, MP4, and MOV for batch rendering. Users can choose to merge the contents of a collection into a single exported file or save each object individually.

The tool replicates the Blender collection hierarchy by generating an identical folder structure on the local drive during export. Users can also designate specific collections containing lights, cameras, or backgrounds to be included in every export automatically.
