i use this script for importing paint effect animation and facial animation from advance skeleton to ue4, you can also use it for any deformer effect or cloth simulation
you can use this script to turn any skeletal or vertex animation into morph animation (as long as it doesn’t add or remove vertices).
that rose animation in beginning of video is actually paint effect animation imported to ue4.
this technique also takes a lot less space compare to alembic.
in one of my tests, exporting a full body character with animation as alembic took 466MB while exporting the same character as morph animation took 40MB.
i hope you guys find it useful
