I’m trying to make a smart material for aged rusted paint. It is prety easy to have good edge wear results with pointiness (or AO in 2.8) and some rust spots with the noise texture.
the part that I cant figure out is how should I tackle is the streaks.
My idea is to fade the rust spots along -Z and have something like that
The first probleme is that I dont know how to set up my nodes to spread the dots.
The second is a bit more complicated and is how to make the streaks follow a curved surface
