Mods & Workshop

Popular DayZ Mods

Community Framework (CF) - Required for many mods
VPPAdminTools - Server administration
Expansion - Vehicles, helicopters, missions
BuilderItems - Enhanced building
Trader - NPC trading systems
BreachingCharge - Raid mechanics
Dabs Framework - Modding framework

Installing Mods from Workshop

Subscribe to mod on Steam Workshop
Copy from workshop folder to server:
steamapps\workshop\content\221100\{modid}
Rename folder to @ModName
Add to startup: -mod=@CF;@VPPAdminTools
Copy required .bikey files to keys/ folder

Mod Load Order

Always load Community Framework first
Load dependency mods before mods that require them
Use semicolons (;) to separate mods, no spaces
Mod folder names are case-sensitive on Linux

🔧 Troubleshooting

Server Won't Start

Port in use: Check if 2302 is available with netstat
Missing dependencies: Install Visual C++ Redistributable (Windows) or lib32gcc1 (Linux)
Config errors: Validate serverDZ.cfg syntax
Mission not found: Verify mission name in serverDZ.cfg matches workshop files

Players Can't Connect

Verify firewall allows UDP 2302-2305
Check BattlEye is running (required for official servers)
Ensure server and client versions match
Verify all mods are properly loaded and have valid .bikey files

Persistence Issues

Tents/stashes disappearing: Check storeHouseStateDisabled = false
Storage corruption: Enable storageAutoFix = 1
Loot not spawning: Delete storage_X/data/*.bin files to reset economy

Mod Conflicts

Check server logs in profiles/ folder
Verify .bikey files are in keys/ folder
Test mods individually to isolate conflicts
Ensure mod versions match between server and clients

Performance Optimization

Server Configuration

# Startup parameters for performance
-cpuCount=4 -limitFPS=60 -dologs -freezecheck

# In serverDZ.cfg
serverTimeAcceleration = 1;         // Reduce if performance issues
guaranteedUpdates = 1;
loginQueueConcurrentPlayers = 3;

Hardware Recommendations

CPU: 4+ cores, 3.5+ GHz single-thread
RAM: 8-16 GB (16+ for heavy mods)
Storage: SSD highly recommended
Network: 100+ Mbps, low latency
