I'm making a total conversion mod and I want to add a new weather overlay. However the game requires a "material" which from what I can see is somewhat locked off. I downloaded a bunch of weather mods and looked into their files to see how they managed it, but it seems they all just used the base game overlays and slightly modified their colours, vectors, speeds, etc. I want to add an entirely new weather overlay with it's own custom material. Is this possible?
