After Effects 24.2.1 exportAsMotionGraphicsTemplate() not returning correct value

This would only work if the Javacsript engine throws an error though, right? It isn't throwing an error, the export call is just returning an incorrect value before the operation is complete.

also saveProject(); is a custom function. try app.project.save(); instead.

You can check, if a try{}catch(err){} struckture inside of a helper function works for you as well.

However: our system runs on AE 23.5x52 right now.

function exportMogrt(comp, replace, filePath) {
    comp.motionGraphicsTemplateName = comp.name;
    comp.openInEssentialGraphics();
    saveProject();
    try {
      comp.exportAsMotionGraphicsTemplate(replace, filePath);
    } catch (err) {
      //alert("Optional Error Message");
    }
  };

Short of a fix for this, would it possible to get some ideas for workarounds? Right now the best I can come up with is a while loop checking that the MOGRT file was actually written before making the next export call.

The CompItem.exportAsMotionGraphicsTemplate() function is returning a value (always false, regardless of apparent success) before the MOGRT has finished exporting. This appears to be causing subsequent export calls to fail, making reliable batch MOGRT export difficult if not impossible.

I am seeing this behavior in AE 24.3 on Windows 10 and in AE 25.1 on MacOS 15..2.

Upon calling CompItem.exportAsMotionGraphicsTemplate(), after the project is collected and the "Creating Motion Graphics Template" progress bar completes there is a significant delay before the final export operation (marked by the "Exporting Motion Graphics Template" progress bar) is carried out.

The script I'm using to test this with is:

function simpleMogrtExportTest(compToExport)
{

	var exportFolder = Folder.selectDialog("Choose a folder to which to export the MOGRT", Folder.myDocuments);
	var success = compToExport.exportAsMotionGraphicsTemplate(true, exportFolder.fsName);
	alert("Success == " +success);
}

simpleMogrtExportTest(app.project.selection[0])

Hi @JohnColombo17100380 if there is any progress on this?
There is already a release of After Effects 2025, but MOGRT is still not exported using the api

Hi John,

Thank you very much for investigating this issue.

This will be of great help for maintaining the compatability of future scripts.

Best,

David
