FlowMap material please

Hi

Does someone have a flowmap material? I can bake the flowmaps. I cant get the flowmap material function to work. I tried various tutorials and im just not coming right with a proper waterflow effect.

Notice the artifacts. I saw other posts on the forums about it. Even on answerhub. And the closest anyone has gotten to giving a simple answer was… buy my stuff in marketplace to see a fix.
I am using the flowmaps material function.

Any answers / tips would be much appreciated

Eventually got it working. What a nightmare. No more artifacts and it flows exactly how i want.
As it covers 3 pools and 2 waterfalls
