You shouldn't expect too much from this, not because it's a bad idea but
because uvs don't take too kindly to being stretched when rendered using
mental ray. For an example, try this:-
Get a one poly grid, put a texture projection on it in x/z and a noicon
texture.
Now, go to the texture editor, select all uvs and scale down to s0-30%. Now
take one corner point and pull it back out somewhere near it's original
position and preview the grid.
