So, rivers are in what I'd call an alpha stage right now. They need finetuning to look better, more natural, and with features (real deltas, mid-river islands, varying river width), but the harder parts are done. At least, I believe so. Unless everyone thinks they look like shit, of course. This is a short post, I just thought I would show a couple of examples of what you can come to expect.
Feedback is very much appreciated, as rivers are very hard, and I want to get them right!
