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?
Honestly I'm not sure. Haven't worked with weather overlays for years myself. Materials are a Unity thing, so if you were to do it you'd have to do it through whatever Unity pathways exist. Maybe there's some Internet help on how to do it.
