Hello, I’m not sure if this is a simple application or not, but what I’d like to do is to have a gradient of opacity (from solid to transparent) based on an attractor point. In looking for this, I’ve seen a color gradient from an attractor point (see below) but I’d like to do the same with opacity…

Post your own code, of course.

Thank you @danielbent for posting something to work with. No need for C# (or R6) though:
