hey guys, so i’m messing around with light functions for water caustics, my level is about 30% water. I tried with point lights but that took performance down too much, so i tried with my directional light and that works great, the problem, as expected, is that it goes everywhere, so i have exported one of my landscape paint layers, figured i could use it as a mask, only i have no idea how to use it properly or if it can even be done in a light function.
small vid of what i have so far:
