Is there any way to use Polygon Packing for a texture atlas that is used by several Spine projects?

Maybe do something weird like somehow copy all of the meshes from all of the projects into a single project or something? :think:

If you want to export from Spine, you can simply import all the skeletons in a single Spine project, (without having to move each mesh into the same skeleton) then export. You can also choose if you prefer to have an atlas per skeleton or a unique atlas for everything. I think this solution is great as you can just deactivate the skeletons you don't need when working on something so that they won't clutter your view, and you have less files to manage.

If you prefer to have separate Spine projects, another way to automate this is to use the command line to pack textures:
Texture atlas packing:
-i, --input Path to folder of images to be packed.
-o, --output Path to write texture atlas and PNG files.
-j, --project Path to a project to determine which images are used by meshes.
-n, --name Texture atlas name, the prefix for the atlas and PNG files.
-p, --pack Texture atlas name or path to pack settings JSON file.

It is possible! But only from the command line:
Spine --help
...
Texture atlas packing:
-i, --input Path to folder of images to be packed.
-o, --output Path to write texture atlas and PNG files.
-j, --project Path to a project to determine which images are used by meshes.
-n, --name Texture atlas name, the prefix for the atlas and PNG files.
-p, --pack Texture atlas name or path to pack settings JSON file.
You can specify -j or --project multiple times. For example:
Spine -i /path/to/input/images -j project1.spine -j project2.spine -o /path/to/output -n atlasName -p /path/to/pack.json
