I'm trying to recreate this cool effect I came across. It looks like an infection system that's getting traced so I started to go down that path.
With a basic infection step-up, I got the leading edge of the infection so I could trace it. I actually don't think that's going to work having had a look at the set up now and wondered if anyone else had any ideas of how to achieve something like this?
