Not yet, but I know where everything has to go now, I spent a lot of time trying to figure out the rendering of particles in UE4, and went a little over the top by creating my own type data for flex fluid, until I realised I only need to change the rendering.
Actually writing the shaders required is relatively easy, same with scene proxies and vertex factories, the way particle rendering is structured is fairly complex looking tho. Will hopefully have something to show today or tomorrow, if all goes well.
