The 1.17 main menu.

File location

/assets/minecraft/optifine/gui/background.properties

Custom Panoramas control the behaviour of the main menu panorama.

Alternative panorama folders

Note

This is optional.

Alternative panorama folders can include a background.properties file to define custom properties for each panorama.

For example:

/assets/minecraft/optifine/gui/background1
    /panorama_0.png
    /panorama_1.png
    /panorama_2.png
    /panorama_3.png
    /panorama_4.png
    /panorama_5.png

Overlay colors

Note

When the top and bottom colors are both 0, that overlay is disabled.

If enabled, two gradient overlays can be drawn on top of the background panorama.

The color format is ARGB (alpha [transparency], red, green, blue), in hexadecimal.

To read it, convert each interval of two values to decimal from hexadecimal (AABBCCDD == 0xAA, 0xBB, 0xCC, 0xDD == 170, 187, 204, 221).

overlay1.top

Values: AARRGGBB
Optional
Default: 80FFFFFF

First overlay, top gradient color.

overlay1.bottom

Values: AARRGGBB
Optional
Default: 00FFFFFF

First overlay, bottom gradient color.

overlay2.top

Optional
Default: 00000000

Second overlay, top gradient color.

overlay2.bottom
