I'm trying to create an area filled with 3 sizes of paving block. All are the same height, just vary on the width. The closest I can get is this kind of arrangement. I tried using a 'full' distribution with collisions at 105%, but the object collision takes effect vertically too.
I've also tried distributing along a line, but this only allows for a constant spacing as far as I can see.
Is this possible with Forest Pack?
