Amazing week 1 submission @procyonlotor! As I said during yesterday’s stream, I’m very impressed by the resourcefulness you’ve displayed with virtually zero direction from me. You get full week 1 points easily 👍
Stylistically the main addition I’d like to see is some white water effects. Not as in rapids but more as a means to identify borders of the stream; where it interacts with the stones and edges of the terrain. It’s commonly called “edgefoam”.

I’ve looked into techniques for this a couple times and have never been able to do it procedurally with shader nodes. Maybe there’s a way to do it but 🤷♂️. Alternatively you could try adding a dedicated strip of geometry along the edges of the water (slightly above the water) with it’s own shader to simulate edge foam. This guide seems insightful (though not with Bender).
