Efficiency Light Indicator(ELI)

Efficiency Light Indicator

Got a MEGA factory and struggling to tell which machines are actually running at 100% efficiency because all the lights are just green? Tired of opening every machine's UI just to check. This mod allows you to customize the color of machine indicator lights when a machine is operating at specified efficiency. You are also able to decide if you want the color to change based on if machine produces above or below your set value for specific machine states: Has crystals, Has Power Shard, Has Error (No Power) , and Standby (Idle).

The color is selected using Satisfactory's built in color picker, using the same style as signs: Hue, Saturation, and Brightness. Color presets are currently not supported.

Fix Sign Button(Disabled)

The "Fix Sign" button was intended for Kinstruction.

This fixes the sign/billboard background bug introduced in the 1.2 update involving: Vertical gradients, Horizontal gradients, Rectangle backgrounds

Important Information

Colors are only updated when one of the following occurs:

1. The Submit button is pressed.
2. The Update Indicator button is pressed.
3. The world is saved and reloaded.
4. The machine changes production state (for example, transitioning from idle to producing).

Automatic updates are currently disabled to reduce performance impact. Also I could not get async timer to work properly where the user can set the timer interval directly. (In-Progress?) This mod was tested using Kinstruction's Cyberpunk Build World 2026.
