Waterdrop animation in Blender

Hello everyone,

I’m trying to animate a waterdrop on a leaf in Blender. I found a great tutorial where is exactly shown what I need.

and the final result:

This was achieved with “Metaballs” and I think this isn’t supported in ue4.
My question is if someone knows some workaround’s or different techniques to achieve a similiar result to get it working in ue4?

Thanks in advance
