Problem with same colour/material

Hi everyone!
I have problem with walls in my game. It is this same material, but on different objects (cubes). The sharp ends of individual objects are clearly distinguished. I would like these transitions to be smooth and invisible. It is visible in the game itself and in the scene view.
Thanks for help.

I guess I can leave it like that. I can’t get the perfect color, but it’s not too bad. I just change material metallic to 1.
