A tool to make dry streams?

Something like that. I mean in a depth map . Is there a cool modern solution? Kind of stream simulation or something?

Do you have any examples? I have a feeling it's never going to be quite realistic there without complex particle simulation

I would use World Machine, hydraulic erosion.

I would love to see how would that look like.

I tried World Machine . Maybe haven't dug it deep enough but what I get is rather smooth blurry something working only on steep mountain sides and looking nothing like a river or a stream.

I actually did it years ago with now defunct soft Geocontrol. Couldn't now run it even with winXP compatibility mode. It had a special "river" tool that could make it pretty nicely without much of a user input. Couldn't find anything close to it in World machine.

On youtube I saw a few realtime simulation done on

GPU as a research projects . Sometimes they does look promising.

Been awhile since I used it, but I would change the hardness of the landmass, and decrease elevation. Look for the Grand Canyon examples.

There's also World Creator for Unity:

...looks fairly straightforward generating roads/rivers and reading documentation for recent feature updates which seems to support hydraulic erosion:

EDIT:

Known Issues:

"Memory issues for resolutions above 4096 x 4096 when using the Adv. Erosion filters and those utilizing the new Simulation Filters including the new Flow map system."

Thanks for the advice Eric, I think I need to dig WM a bit extra.

As of World Creator I bought it couple years ago just because it's what Geocontrol evolved into. Surprisingly it has nothing like old Geocontrol river tool. And this one in the video lets you make a kind of water river with banks but nothing like old dried out stream through sand/clay type of soil . They have a water simulation tab but it also working noting like that, rather like a in game low res water simulation.

I've had good feedback on gaea from our terrain artists, mainly around speed and ease of use over worldmachine.

I'd use designer tbh. Given a flow map you could produce some pretty plausible results

Thanks Eric for the picture and link. Looks nice indeed but I want the main river stream separating into to multiple smaller streams in turns and intertwining each other with a bit of real physics hint . Like a real stream changing its course sometimes through its sandy bed.

Thanks poopipe. The soft looks really promising in many regards. I have a question. Why when I try to output in higher resolution it seems like doing kind of irregular tiling instead of doing really more hires image? Is it supposed that way?
