Backlights

Backlights

Backlights light up a hologram so it stays readable at night or in dark areas. The mod places a vertical column of invisible minecraft:light blocks behind the hologram, the same block type WorldEdit uses with //set light. Every block in the column emits at full brightness (level 15) with no visible model.

Command

/eh backlight <id> <on|off|toggle> [height 1-10]

• on - enable the backlight.
• off - disable it.
• toggle - flip the current state.
• height (optional): the column height in blocks, 1-10. Defaults to 3. Only used when enabling.

The <id> argument tab-completes from existing holograms.

Examples

Enable a default 3-block column:

/eh backlight spawn_info on

Enable a tall 10-block column for a large board:

/eh backlight top_kills on 10

Turn it off:

/eh backlight spawn_info off

How It Works

• The column starts on the ground directly below the hologram and rises straight up. For tall holograms (like a Top-10 scoreboard), the column spans the full height, from the lowest line up through the top line, so no rows are left dark. The configured height acts as a minimum.
• It never overwrites player builds. Only air and water cells receive a light block (water stays waterlogged); any cell already holding a solid block is skipped.
• Backlights follow the hologram when it moves or teleports.
• They persist across /eh reload and server restarts, including on scoreboard holograms.
• Deleting a hologram removes its backlight automatically.

Permission

Toggling backlights requires the eliteholograms.backlight node (OPs always have it). See Permissions.

Notes

• The minecraft:light block exists in Minecraft 1.17 and later, so backlights are available on all supported editions (Forge 1.19.2 and 1.20.1, NeoForge 1.21.1 and 26.1.2).
• If a light block does not appear, the cell directly there likely already contains a solid block; the column skips occupied cells by design.
