2d Texture repeat direction

I have 25x25 cubes at scene. I give it a texture with Tiling- offset settings. But i have problem about cubes at corner. i want it repeat like at top surface so i cant see it like 3D object. But as u see it doesnt cover other surface like i want. How can i solve this ? Do i need a shader ?

* You can think like i am adding circle texture to box object and i expect it looks like cylinder.

 

A box is just a box. Think of it like a cardboard box. If you paint part of the outside of a box red, then cut out the areas that you didn't paint, you're just going to get a box with a big hole in it. The same thing is happening here. If you want it to have some kind of volume to it, the easiest solution is to fake it and not use a box at all. Just use multiple quads stacked on top of eachother. As long as you don't let the camera get too far to the sides or too close it'll look just like a solid object that's been sliced through. Really, the shader-based solutions that you would do would be doing the same thing, just raytracing the planes in the shader instead of having them as geometry.
