chest.png-atlas in Java Edition 1.21.6.

chest.png-atlas is a procedurally-generated texture atlas used to store textures for all chests.

Format

chest.png-atlas is a fixed-width 256×256-pixel file that store textures for all chests.

History

Java Edition
1.15Pre-release 1Added chest.png-atlas, following the splitting of textures-atlas.
1.19.322w42aAs an optimization to resource pack loading, everything in the relevant directory is compiled into this atlas, rather than only those sprites which are used by the game. For this specific atlas, there is no resulting visual change.
22w46aA customizable atlas json file has been added which can be used to control which graphics are added to this atlas.
1.19.4Pre-release 3The way in which sprites are arranged on atlases has been changed considerably, resulting in atlas dimensions being generally smaller.
This atlas can now be exported to the screenshots folder using F3 + S.

Versions of the atlas

Game version Atlas Changes Notes
Main Development
1.15 Pre-release 1 Introduction
1.19.4 Pre-release 3 Rearranged due to packing optimization
1.20 23w14a Updated large chest textures[1]
23w13a_or_b Added Golden Chest

Mipmapped versions

Minecraft also generates mipmapped versions of this atlas, for unknown reasons. They are not used by the game at all - only blocks placed in the world which use the json model system use mipmapped textures.[2]

Trivia

  • Were all chest textures split and handled like block textures are with individual 16×16 sprites, the atlas would be half the size.
