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 20MB or smaller.
File size limits for each bundle depend on whether you're publishing to Facebook or Instagram. Find out more.
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 Export in the Toolbar and follow the instructions. You'll see a warning if it's still too big.
