I added a splash to the waterfall.

It’s a basically a vertex shader that uses a sine wave with a varying amplitude. The jagged effect is because the plane only has about 10 vertices on the top side, so there’s not enough to smooth it out.
The aesthetic definitely clashes with everything else, but it’s mostly just a placeholder for now.
Think of it like a scaffolding. Will be tweaking it with different textures and styles moving forward.
