I would LOVE to see you guys do a super customisable ink and paint shader. I think the features you guys could come up with would be great and it fits really nicely into the archviz pipeline to have a shader you can use to show concept visuals in that way.
+1 , sketchy/expressive lines within a “photoreal” render can be a good contrast.

Having the option to present sketchy visuals makes the entire process of dealing with clients less hassle imho
Just FYI Not looking for a falloff workaround i want a REAL purpose made shader!
