I have seams in my tiles

hi
i have made some tiles in photosop i see no seams at all,
but when i put it on my mesh i see seams .
The mesh is made with probuilder ,i extrude a cube or a plane
and drag and drop my materials on the selected faces.

 

Try setting your texture wrap mode to "clamp". Your filtering is most likely picking up pixels from the opposite side of the texture.
