I think your trying to achieve something like this?
The main thing to remember here, is that even though a cube is 1 unit, it's actually 2 wide, 2 high and 2 deep. So, to move a cube like that, you need to move it, twice it's scale. All the stuff for that grid is based on the scale variable. The texture is just a single square. It is scaled:
So it fits the cube properly and doesn't scale along with it. I position the cube using x,y and z co-ords according to the grid scale. 1,1,1 is the bottom left, closest corner. To position the cube:
(scale*2)/-2 + x
scale*2 <<< because a normal unscaled blitz cube, is 2 wide/high/deep.
/2 <<< divide all that by 2, because you taking the positioning from the middle of the cube. IN theory, the *2 and /2 cancel each other out, but it's good to see whats happening.
+x <<< add on the co-ords to offset the cube to it's place inside the grid.
I hope that helps and i hope it's what your after :o)
