I want to make some bricks just for the fun of it and also make some unusual bricks too. I understand the script pretty well and an icon for the brick. But if I were to make a 1x2 brick(just example) would I use a 1x2 are in blender? By that i means 2 boxes wide and 1 box high and 1 box for length? And what is a BLB file? I cant open it so I'm kind of stuck here. Please help if possible.
