Anyone know how to layout the sea foam mask?

Unity Engine
1

I zeroed out everything on the demo island level to preserve the scripts and set up. Once I did I found the sea foam edge which looks so cool is a placed mask. I’m new to Unity so I haven’t a clue how to lay it out and there’s nothing in the documentation covering it. The effect seems to be a tile but the mask seems to be placed in some manner. I can’t figure out how to place it or erase it. Anyone know the process?

Thanks

It’s just a mesh that an artist created and placed manually.

I’m thinking export the heightmap back out and use that to trace the waterline with a path in your 3D app, then convert to mesh and extrude the path to the desired “foam width”, then import that geometry and place it just so. Repeat as needed until it looks right. No magic foam just yet.

Or you could generate the foam mesh procedurally - take the heightmap from the terrain, and place foam strips whenever heights cross water level. Of course an artist-tweaked mesh would always look better (in hands of good artist of course).
