A few days ago, Allegorithmic released a new version of Substance Painter version 2017.2 with a few feature called Anchor Points that allow you to incorporate your generator details into your brush stamps. I also show the MatFX edge wear detail filter to get similar results and a simpler setup at the cost of flexibility.
I should add that Edge wear is not the sole purpose of Anchor points in Substance Painter, but was just for the scope of this video.
In this video we look at the new Anchor points feature in Substance Painter 2017.2 as well as the recently added MatFX edge wear filter to see how they're set up and why you would use either or.
