I was tired of using smaller bricks to make the ceilings of rooms look the same so I edited the brickBOTTOMEDGE.png file to create a seamless texture. Now the ceilings are seamless, and bigger bricks can be used for the floor/ceiling without having to sacrifice looks. In the picture I show this because the bricks are different colors but as you can see at the seams the texture continues so if I painted them the same color, you could not tell they were different bricks.
If you want to do this to your Blockland, replace the brickBOTTOMEDGE.png in the base/shapes folder with the one attached. I would reccomend backing up the original though in case you want to change back.
