Hexagonal Grid

tutorial for what? all you have to do is make that the alpha layer so that the black is hidden and the white shows

but you shouldnt do it that way, because if you take a render from the side, sometimes it will be blurry; and if you lower the blurryness, then it will look like there is no AA on it

in other words... its known as the "opacity" (or atleast it is in 3dsmax materials wise) but its called alpha layering

white stays, and the black appears to be gone
