When you export an effect from Spark AR Studio, an .arexport file will be saved to your computer. This file contains everything your effect needs to work in the camera.
It's important to check the file sizes when you're exporting an effect. Effects that are too big won't be approved.
The .arexport bundle that's exported on to your computer must be 40MB or smaller.
File size limits for each bundle depend on whether you're publishing to Facebook or Instagram.
Make sure you've tested and debugged the effect before exporting it.
When you're happy with your effect and you've checked the file sizes, click File > Export and follow the on-screen instructions. You'll see a warning if it's still too big.
You can also batch export multiple projects using the command line tool.
