The dimension switching screen.

Custom Loading Screens define the screen when changing worlds, loading a world, starting the game, or reloading datapacks.

File location

/assets/minecraft/optifine/gui/loading/loading.properties

Custom loading screen backgrounds per dimension can be defined as: /assets/minecraft/optifine/gui/loading/background<DIM>.png

Where <DIM> is the dimension ID:

  • 1: End

  • 0: Overworld

  • -1: Nether

Note

Mods may extend this ID list.

Properties

Note

The properties scaleMode, scale, and center can also be configured per dimension:

dim<dim>.scaleMode=<fixed|full|stretch>
dim<dim>.scale=2
dim<dim>.center=<true|false>

scaleMode

Values: fixed, full, or stretch
Optional
Default: fixed

Custom scale mode for the background texture:

  • fixed: use fixed scale, pixel for pixel (default).

  • full: fullscreen, keep aspect ratio.

  • stretch: fullscreen, stretch picture.

scale
