■ New Features

More “Chat” conversations


LUMI characters now have many more new “Chat” conversations with each other.

  • Available in Korean, English, Japanese, Simplified Chinese and Traditional Chinese.

Character summoning


You can now set summon candidates and the number of characters that appear at startup separately on the “LUMI” tab in Settings.

  • Characters selected in “Choose Character” become summon candidates. Changing the candidates does not affect characters already on screen.
  • Set a “Number at startup” for each character in “Summon characters”, and that many will appear from the next launch.
  • Use “Summon one selected character” to instantly summon one more of the character you want.

Broadcast layout


On the “Broadcast” tab, you can now bring LUMI and Bongo LUMI into OBS separately and adjust their positions.

  • Use “Copy character source” and “Copy Bongo source” to add each to a different browser source.
  • Choose what the existing address shows in “Default source”.
  • Use “Move characters” and “Move Bongo” to move them pixel by pixel on the broadcast screen, and “Reset positions” to restore them.
  • LUMI's position on the desktop does not change.
  • The “Behaviour” and “Broadcast” tabs now show which behavior settings you are editing (Normal mode/Broadcast mode), and “Open behavior settings” takes you straight there.

Restart


A “Restart” option has been added to the tray menu and the Settings window so you can restart Little LUMI right away.

  • Select it at any time from the tray menu, just above “Quit”.
  • While mod changes are waiting to be applied, “Restart” also appears at the bottom of the Settings window.
  • Selecting it saves your changes and then restarts.

Instant settings save


Every value you change in the Settings window is now saved immediately, without pressing “Apply”.

  • Only “Close” is shown now, without “Apply” or “Cancel”.
  • Size and opacity are applied as soon as you release the slider.
  • Changing LUMI's size no longer re-summons LUMI, keeping its position and current action.
  • When a change requires quitting and relaunching, such as turning a mod on or off, a “Restart” button appears.

Mod management


The “Mods” tab now makes it easier to check the status of your mods.

  • “Enabling” or “Disabling” appears before a mod's name while it is being turned on or off.
  • Turning mods on or off and changing their order, including character mods and voice packs, takes effect from the next launch.
  • Optimized the mod loading process.

■ Bug Fixes

  • Fixed LUMI on a secondary monitor continuously falling without landing on the ground when “Move between screens” was turned off.
  • Fixed LUMI's right-click menu being cut off at the edge of the screen when it had many items.
  • Fixed menus not closing when briefly clicking outside them.
  • Fixed text being cut off when moving the Settings window to a monitor with a different scale.
  • Fixed characters without a partner of the same kind repeatedly taking turns showing the “Playing Together” failure message.
  • Fixed characters other than LUMI using LUMI's speech style in Focus Mode messages.
  • Fixed the startup notice for code mods being hidden behind the Settings window and becoming inaccessible.
  • Fixed Workshop mod titles and descriptions being shown in the Workshop's default language instead of the app language.
  • Fixed item names being hard to read when expanding groups on the “Behaviour” and “Sound” tabs after switching the theme to Dark.
  • Other tooltip and wording fixes.
