IronhordeLighting
Updated for DayZ 1.29

IMPORTANT!
DayZ currently has a lighting bug (since many years back), that Bohemia Interactive (the developers) knows about. It's been documented and reported numerous times, and they have it in their list of things to fix, and have said that there is a patch coming for it in the future. The bug itself makes lights flicker when placing more than 3-4 lights in a closed space, as well as not all emitters being visible at the same time, depending on distance. When that is fixed, this mod will be updated to be even more advanced.

Description
IronhordeLighting is a custom DayZ lighting and ambience mod that adds a large library of placeable light sources, atmospheric effects, warning beacons, searchlights, flicker lights, environmental heat/fire props, and LED strip variants for mapping, base design, bunkers, industrial zones, and custom scenes.
The mod is built around configurable lighting behavior, letting server owners tune brightness, color, radius, beam behavior, pulse/flicker patterns, and other light properties from the config instead of being locked into a single hardcoded look. EVERY light can be configured independently, with a lot of settings!
I have taken some inspiration from other games and mods, but everything has been done from scratch.

Updates:
v1.4 2026-05-24
Fixed a bug:
"IronhordeLighting/Scripts/4_World/ironhordelighting\poweredstructurelamps.c,775": Overriding function 'RefreshConfiguredLight' but not marked as 'override'"
Thanks to Mithrandir for reporting it!
Added 6 more police lights, blinking static blue/red/white to use as static policecar headlights/taillights:
IH_PoliceLight_Static_Forward_Flash_Red_01
IH_PoliceLight_Static_Forward_Flash_Red_02
IH_PoliceLight_Static_Forward_Flash_Blue_01
IH_PoliceLight_Static_Forward_Flash_Blue_02

IH_PoliceLight_Static_Forward_Flash_White_02
Thanks to HourglassRemains for the suggestions!

Configuration
The mod creates a profile config file at:
profiles\IronhordeLighting\ironhordelighting.json
That file contains entries for supported light assets, allowing admins to adjust behavior without editing scripts. Depending on the light type, configurable values include:
- brightness
- color
- radius / fade radius
- beam length
- rotation speed
- beam width / pitch
- pulse and strobe behavior
- flicker behavior
- ambient color contribution
- RGB cycle speed for RGB LED strips
This makes it possible to fine-tune the entire lighting package to fit different server styles, from dark survival ambience to brighter cinematic or roleplay-heavy setups.

IMPORTANT LINE IN THE CONFIG FILE
- lightingconfig: 0 = normal configured brightness
- lightingconfig: 1 = boosted brightness mode
In the current setup, lightingconfig: 1 applies a 3.0x brightness multiplier, which is useful for servers that want stronger visibility from the same placed light assets without having to rebalance every individual entry by hand.
Use the same as you have in your serverDZ.cfg, unless you want to tweak it on purpose.
The config file will be created on first server start.

Mod Repack / Server Pack
You are allowed to repack this into any server modpack as much as you like,
because I'm not an epic-teared kid about these things, like some ;D
