Now you can restyle your Minecraft buildings giving a new painting layer to the walls.
Wall Painter 1.7.2 and 1.7.10 is a mod that adds two new items into the game. The first is a roller which can be used to apply the paint to the walls or at blocks, using the 16 basic dyes of the game. The second object is a paint scraper which will allowyou to remove the paint from a block or a wall.
