Tri-planar Projection Tiling Issues with substance?


I’m using a tri-planar projection function and it works fine for any texture apart from all substance textures I’m trying. I get this tiling problem on all substances I’ve tried. Posted this on Allegorithmic aswell but feels like this is the right place. I have tried exporting from both substance designer and substance painter. Problem exsists within every layer of the texture. What can cause this problem?

The line is very visible in game!
