How to fix a SD shading error?

I’m picking up these triangles on this SD material I created and the straight lines look great yet these pop up in the UE4 editor. I went back to the file and found the lines are jagged. I’m trying to fix it with a Blur node and Levels to even it up but it isn’t going very well. This mask is a zoomed in image of a 4x4 tile through the Tile Generator node. I’m assuming this is the problem but could be wrong. The material looks great in the SD 3D view.
