Lottie-web: Track Matte Not Working

• Browser and Browser Version: Chrome 68
• After Effects Version: CC 2018

I created a file in after effects that includes track matting. Using bodymovin, I created a .json file and attempted to use it in lottie and found that the track matting was not being applied to the shapes in the file.

Hi unfortunately the Set Matte effect is partially supported.
Track Matte has better support. You can try that one out.

That explains it! I didn't realize the difference between the two (I'm very new to using after effects). Thank you for your help! :)
