I’m looking into creating a material function which would plug into my Landscape master material, and provide rain/water flow that follows the shape of the terrain. In other words, wherever there is a slope, pan a texture downhill.
Here is what I have so far:
However, as you can probably see in the video above, things don’t work quite as intended. The areas between each of the “sides” should gradually change the direction of flow, rather than forcing it into one of the 4. There also seems to be some sort of seam or gap between there as well.
Any ideas, perhaps a simpler way to do this than I have?
