Any way of exporting Animation Deformers from UE as fbx?

I’m looking for a way of exporting (out of UE) animations done with the new animation deformers as fbx. So far, whatever I’ve tried will not transfer the deform animations.

Well if you just want the deformed animations you could export as a Alembic file.

Thanks for the question!

Since your animation uses custom deformers, which are not yet standardized across different applications, file formats, the most straight forward way to keep your animation the same in other software is to export it as some type of cache.

In 5.6 there is a new experimental plugin called “GeometryCacheLevelSequenceBaker” that allows you to bake skeletal mesh animation in a level sequence into a GeometryCache asset, which can then be exported out of engine as a USD file if you also enable the “USDImporter” plugin. You can give it a try in 5.6 Preview 1 and see if it works for you.
