Waterfall Creation in UE4?

This is probably a simple procedure, at least I would imagine that it is. I am looking to create a massive waterfall in UE4, and eventually a series of waterfalls and rapids to follow. Is there a spline system that comes with the engine to accomplish this, or do I need to create my own?

You can check this method of creation waterfalls in UE4 (used by ARK)ARK Dev Kit Lesson: Rivers & Waterfalls - YouTube
At it’s core is basically a planar mesh with panning textures, but you can use splines to place your own meshes.
Hope it helps.

Yea the basic idea is meshes with panning textures and particles for simulating drops, splashes and mist here and there.
