Texture tiling from atlas

Hey,

I was wondering if anyone has idea on how can do this: Tile texture from atlas in similar manner to photoshop's patterns or Construct 2 tiling or UDK brush texture tiling. Which is basically you don't set tiling from material. The tiling happens based on mesh size, so if you have a brick wall texture, it will start rendering texture from plane's top-left side, as you scale the plane and it's area increases the bricks are "added" because texture is repeated.

This image should kind of explain what I'm talking about. http://imgur.com/m4qKdUp

So in 2D game, I would create this tiled texture and scale the plane and texture would be repeated, so for walls and stuff like that I could have 1 material and 1 plane to create walls, thus less draw calls.

The problem I have is finding this kind of solution that works with a) Atlas b) Mobiles

if anyone can give me any suggestions that would be awesome.
