The AbcExport plugin is used to write an Alembic file. It contains a single command named AbcExport. It isn't a file translator so it can write out multiple files with different settings while only stepping through the frame range once. To write out the entire scene from frame 1 to 100: AbcExport -j "-fr 1 100 -file scene.abc"; To write out only your selected shapes (and it's ancestor nodes): AbcExport -j "-sl -file scene.abc"; Other options can be viewed via: AbcExport -h;
