If a player head is created that has specific strings in its profile data, the contents of atlases will be used as the head’s texture.
Example command: /give @p player_head[profile={texture:"atlas/blocks"}]
Other atlases can be viewed by replacing “blocks” with other strings, such as “gui”.
The fix to this is easy: simply move texture atlas locations up one level. Currently they’re stored at, for example, “minecraft:textures/atlas/blocks.png”; we could change this to “minecraft:atlas/blocks.png”, “minecraft:atlases/blocks.png”, “minecraft:texture_atlases/blocks.png”, or any other desired variant; this way, we don’t get atlases unexpectedly being displayed in situations where they should not be.
Thank you for your report!
