Export and Import to After Effects manually
You can export data when After Effects is not connected and save the data file for later usage or to pass over to a colleague.
Don't click 'Connect to Ae'. Instead leave the path blank. Now when you select and export object data it will create a 'BlenderAe' folder with the data file and a script file in the users 'Documents' folder.
In After Effects go to 'File>Scripts>Run Script File...' and select the script file located in the BlenderAe folder.
You can move the files wherever you like but both the ‘BlenderAe_data.json’ and 'BlenderAe_Import.jsxbin' must remain together in the same folder.
