Exporting non-standard animation properties from Blender to Unreal,Exporting animation on non-standard properties from Blender to Unreal

Hello All,

I am trying to export the following animation from Blender to UE4.

This is what it currently looks like in Blender

However, when I export to UE4 through the Alembic format, I lose the curve animation.

This is what it currently looks like in Unreal

Any idea’s on how I would best go about exporting animation on non-standard properties (example : animating the start/end of a bevel along a curve?). I guess there should be some way to bake it down but I’m having trouble getting it to work.

All help appreciated!
