How do I make so a material has same size on all surfaces/objects?

For example: In real life, all clay bricks are about the same size no matter what building they are a part of. How can I Make such material, so that as soon as I apply it to an object, it get’s its true size?

You’ll need to make a material that taps into the WorldAlignedTexture and WorldAlignedNormals nodes. I haven’t done this myself, so there might be some tricks to deal with the object’s rotation.
