title: How to remove a texture from one side of a cube in Unity 5?
body: <p>I'm building a visual city in Unity 5 and I used some textures for my buildings. But the problem is whenever I adjust a texture a cube ,it sets all of the sides of the cube to that texture.. I mean I want to remove the roof side texture because there's no building in the real world which has windows on the roof ! <em>As you can see in this image:</em></p>
