Hi there, for numerous Alpha Erosion and Smoothstepping functions I typically have to create a “path” and I would like it mapped from black to white by following the trail course.
For “linear” stuff it’s no difficulty because it’s only a matter of overlaying a gradient with a sure angle, however i’m puzzled concerning how I could make this gradient comply with the course of a path.
I’m including a horrible drawing I swiftly painted, in hopes of creating my query extra comprehensible.
Anybody bought an concept?
P.S: Bonus factors if I don’t have to make use of Adobe Illustrator 
but when there’s a solution to do it there, I’m up for it!
