Animating point clouds?

Ok so I have this point cloud and I need a way to swirl the points as if they are a organized floating set of particles that represent a terrain. Here is the effect Im trying to recreate Point Cloud SandBox 0.2 on Vimeo

Here is my point cloud

Well the short answer is that I don’t think you can do this in UE4, you’ll probably need an animation program. For such a complex task my first idea is to use something like “realflow” or so and export the animation to FBX.
