Uploading and Exporting Effects

To publish your effect, you must add it to Meta Spark Hub. There are two ways to do add your effect: either upload your effect directly from Meta Spark Studio or create an export file first.

Upload directly

You can automatically upload your effect to Meta Spark Hub without having to create an export file at all.

  1. In the toolbar, click the Publish icon.
  2. In the Publish window, follow the on-screen instructions.

Interface with the publish window open

In this window, you must:

When you’re happy, in the lower right, select Upload and Meta Spark does the rest! Meta Spark Hub launches once the effect has been uploaded.

Continue the rest of the publishing process in Meta Spark Hub, following the advice here.

Create a .arexport file

You can also create a Meta Spark export file (the extension is .arexport) and manually upload it to Meta Spark Hub. This export file contains all the individual files needed for your effect to work on your chosen platform.

To create the .arexport file

  1. In the toolbar, click the Publish icon.
  2. In the Publish window, follow the on-screen instructions.
  3. When you’re happy, in the bottom left, select Export.

Checking the export file size

When you've exported your .arexport file, it's important to check it meets the 40MB size limit. Please note that this 40MB limit is for the .arexport file only. Your actual effect files must be much smaller.

Meta Spark Studio won't check the file size for you, you must use your own computer to check the size. Alternatively, you get a warning when uploading your .arexport file to Meta Spark Hub, if you try to upload it and it’s too large.

Once exported, upload it to Meta Spark Hub to complete the publishing process! If you’re not ready to publish, save your exported project in a shared folder. This helps when collaborating over time.

Batch exporting projects

You can also batch export multiple projects using the command-line tool.
