so i made a house with 1 brick thick walls and it doesnt look pretty because the outside is the same color as the inside. So i thought that someone could make a brick that was either 2D, which might not work because the face may disappear, or a very thin brick sliver. This would then enable you to cover an entire wall with these bricks and have a different color on the inside than the outside.
some of you may say, "use 2 brick wide walls" well i say forget you cuz i dont like how thick and stuffty that looks. i just need something i can paint another color but not take up a whole lot of room. And it would be default no colliding or ray casting.
