So for my game I am looking to have the glass exterior windows to look like they are being hit with water, like a dripping, rain hitting sort of effect, I’ve tried a couple things but can’t seem to get what I want. I have tried a normal map(of rain splash texture) with a panner and using it as a mask and that looks almost right, I’ve tried messing with particles to see if any would fuction the way i like…So far no luck, so if any knows where there may be a tutorial or has a idea of how I should get started it would be very much a appreciated, thanks in advance.
