blocks.png-atlas

blocks.png-atlas is a texture atlas used to store all block textures and some block entity and entity textures.

blocks.png-atlas is a fixed-width 2048×2048-pixel file that is split into different 16×16-pixel squares for most blocks and items. Only the top left 1024×512 corner is actually filled with blocks and items in the base game default textures.

The following textures are included:

• All block textures
  • Including item frames and glow item frames.
• All fluid textures
• Conduit eye, closed and open^[1]
• Conduit shell, closed and open^[1]
• Conduit wind^[1]
• Bell^[1]
• Enchanting table book^[1]
• Block breaking animation
• Missing texture
• Debug textures

Like other atlases, blocks.png-atlas can be produced in the game's screenshot folder by pressing F3 and S in 1.19.4 Pre-release 3 and onwards. In prior versions, however, the atlas is often hidden.

As the UV mapping for block and item models is unbounded, custom models can be used to view the atlas in-game in full, though high-quality copies will not be obtainable through this method.

From 19w41a, resource packs can also display the atlas using shader tricks. This can be used to view several different atlases before changes in 21w10a make this impossible. An example resource pack can be found here in the Minecraft Commands discord server alongside instructions.

Up to four mipmapped versions of each atlas are also generated by the game, depending on the current values in Video Settings. The textures would be shrunk to 8×8, 4×4, 2×2 and 1×1, and would render instead of the normal textures at far distances or sharp angles of incidence.
