Creating Animations With Haiku + Exporting To Lottie

I keep reading about the limitations of After Effects when it comes to creating Lottie files.

Similarly, I’ve been reading about people using different programs like Haiku or Spirit or Greensock to create the same animations before exporting to Lottie.

Has anyone tried this?
