Sharp zig-zag patterns along the edges of my materials ;(

Hello fellow substance designers,

I'm pretty new to substance designer, I've probably only used it for anywhere between 5-10 hours and I keep on running into the same issue and can't find an answer to it anywhere. In the images I've attached, you can see this little sharp zig-zag patterns that run along the edges of some of the materials that I've been working on. I don't know exactly how to describe them, maybe you can see what I mean in the images. I know you can't see them from a distance but they're not nice to have and I'd like to know if this was a normal occurence or if there is a way to get rid of them?
