I am new to the Unreal Engine and I have a question about how water systems work. I am trying to make a wintery forest stream/river inside of a gaming environment and I cannot figure out how to get the river to pull out animated and looks like a river that I can scale along the path that you see highlighted in the texture vaguely. I believe that dark square type shape is supposed to be the river but on the tutorials it looks so much more fluid and clean when you drag it out, much more like a river that embeds depth into the ground where you lay it. But, I cannot seem to get anything of the sort for a reaction when I take it out of the actors list. Can anyone give me some pointers to help me get it right?
Edit: I get a build error that says I need a landscape for the water to be rendered. Which is odd because quite obviously there is a landscape. I put in a new landscape and made it an editable mesh, and I got improved results after I restarted the engine. But, I do get that error. It is deforming the mesh now, but it is obviously still not working like it should.
