Isn't that what OP is trying to suggest?
He's trying to suggest a type of hexagon bricks that defy the way Blockland brick physics work. How about somebody actually makes hexagon bricks first? Then somebody can bypass overlapping for them. I actually need plain normal hexagon bricks for something too.
Or you can just have the .blb have dashes instead of x/d/us to allow bricks to be placed in those parts.
dashes cant overlap dashes.
Thats why you cant place a modter brick inside another modter brick.
it looks like the request is to turn those shapes into bricks, and not an actual hexagon brick with diagonal sides
