How to Edit the Blocks in a Minecraft Texture Pack

"Minecraft" is a block-based computer game that allows players to construct massive and detailed buildings while collecting resources for survival and fighting off monsters. The game is supported by many third-party texture packs that serve to change the default look of the game into something more visually interesting. Sometimes, though, it's necessary to tweak these texture packs either for aesthetic or thematic desires. The look of all the game's blocks can be changed by manipulating the "terrain.png" file.

Step

Download and install "Archive Utility" or any other program capable of decompressing ".jar" files. Any program designed for .zip files will work with .jar files.

Step

Locate the "minecraft.jar" file. On Macs, it's located in your home directory in "Library/Application Support/minecraft/bin". For Windows machines, it's located under "My Computer\Users\"Your user name"\AppData[hidden]\Roaming.minecraft".

Step

Right click on "minecraft.jar" and select "Open With > Archive Utility." This will decompress the .jar file and create a folder called "minecraft" within the "bin" folder.

Step

Open the new minecraft folder and locate "terrain.png." This file controls the look of the different blocks in the game.

Step

Open "terrain.png" in your image editor of choice and make changes to whichever blocks you desire.

Step

Save your changes and close the image editor.

Step

Right click on the minecraft folder containing "terrain.png" and select the option "Compress 'minecraft'." This will create a file in the /bin directory called "Minecraft.zip"

Step

Rename "Minecraft.zip" to minecraft.jar. Your changes to the block designs should appear the next time you load the game.
