This is a shader study that can be used for waterfall animation. I studied because I was working on making custom flipbook animation and one of my friends has a problem with waterfall. I had a theory that using a gradient texture on two lerp textures would work. It works, but it doesn't look smooth as I expected to be. I tried a different approach like adding lerp after paner, but it didn't work because it couldn't handle all the channels. Because of that, I had to bring it to the beginning part and I found lerping one normal texture coordinate and one stretched coordinate works well.
