I’ve been wanting to to pull off a “dirty windshield” effect, where the intensity and vector can be controlled using separate images just like the amount of dirt or grime and small scratches caused by the wiper. (or like my glasses when they’re oily and smeared different directions) and there’s often multiple vectors with my glasses when they’re really bad. …I’m sure there’s a technical name for this. directional blur/smearing?
Progress so far:

(I was re-inspired by this. Thanks CoyHot.)
I haven’t been in the forums for a long time… Hi!
Any feedback is welcome. Do you know a better way?
