i need to add a flow effect to my river so that the water can flow along the path described by the mesh i created. Using ShaderGraph shader i added a time node
multiplied with a screen position
and hooked into a Tiling and Offset node
but the water keep moving in a global direction only.
Please note that i'm using Instant River
tool to create the river mesh

I noticed in its script he's using some methods to rotate and align the UVs, so it should work with any material, but i don't know how to align my shader.
I'm wondering if it's possible to achieve the result with Shader Graph or not. Any idea?
