Hi, I’m using a M_LakeWater shader coming from one of the free assets of the marketplace (Landscape Mountains) but I need the water to flow only in 1 direction, since I have a river and not a lake.
How can I do it?
Thanks, 
You would need to adjust the panner in the material.
That is ofcourse unless the blueprint has any parameters which adjust the panning. In which case you would alter them in the details panel when you have the blueprint selected in the world. (I don’t have it to hand right now)
