What is the best way to export fluids and particles simulations in Unreal Engine? Via the Houdini Engine? Share your experience please.

I'm also looking how to import the fluid mesh and the white water particles/foam to unreal. Anybody?

Houdini Engine in UE4 is better suited to world building and mesh processing. Also, the plugin doesn't allow for runtime processing.

So, your best bet right now for fluid and particle simulations is to use vertex animation textures [www.sidefx.com] to write out the data and read it back in to UE4.
