Nah, I don’t think so. Nothing that will integrate it smoothly with the texture (and then may be with varying the size of blur on different edges. Except of course a shader or NME. I can’t think of an existing one but I don’t know them all. May be someone else or @PatrickRyan if he has a minute would know of a pre-existing you could rapidly twist and tweak to your likin?
Edit: Actually just thinking of it. May be you could twist it from the base of a toon shader @Lun created some Could be something to use as a base? Not sure though, it’s just an idea that came to me like that.
