How to scale material in unity editor

Hello!

I have cube and sphere that I am trying to add a material(With bumpmap) that looks like pebbles. The sphere looks fine with the material, but the pebbles appear too small on the cube. I was wondering if there was a easy way to change the scale on the material without creating a new material. Thanks.

No, the scale of a material is a property of that material, so if you want a different scale you need a different material.
