Yep, or a longish simple shape shader.

Dune: Can you tell me how that shader works since I never used it ? :/

The Simple shape shader has docs with some example projects at:

http://www.planetside.co.uk/wiki/index.php?title=Simple_Shape_Shader

It still needs to be updated for TG3 but all of it applies still. You can find docs for most nodes by clicking the "?" button in the top left of node parameter views.

Regards,

Jo

Try this.

When I use this I get a VERY sharp edge to the river ...

Increase edge width.

I would save the heightfield map as a bmp file and paint in the river by hand as a depression (dark area). This would give you absolute control over the slope of the shore line as well as the depth and shape of the river.
