Static contaminated zones, the gas areas players need protection to enter, are listed in cfgeffectarea.json in the mission folder. Each area has a name, a position and a size, plus the gas particles that make it visible.

What an area has

  • AreaName and Type: ContaminatedArea_Static is a gas area that is always there.
  • TriggerType: what happens to players inside.
  • Pos: X and Z on the map; a Y of 0 puts it on the ground.
  • Radius: the size, in metres.
  • PosHeight / NegHeight: how far the area reaches above and below the position, in metres.
  • Rings and particles: InnerRingCount, InnerPartDist, OuterRingToggle, OuterPartDist, OuterOffset, VerticalLayers and VerticalOffset place the visible gas; ParticleName picks it.
  • Player effects: the particles around the player and the screen tint while inside.

The file also lists safe positions: where players are moved to.

Add, move or remove a zone

  1. Download cfgeffectarea.json and keep a copy.
  2. To add a zone, copy an existing area entry, give it a new name and change Pos and Radius. Keep the particle names as they are.
  3. To remove a zone, delete its entry, and mind the commas between entries.
  4. Check the file with the free DayZ File Checker, upload it and restart.

Editing with Law's KillFeed

On Xbox and PlayStation servers, the dashboard's Server Files page shows each area as a card with every value explained on the paid plan, plus the safe positions. A missing comma is caught before the file is uploaded.

Questions

Can I make a zone smaller?

Yes. Lower its Radius, and the ring and particle spacing if the gas looks too dense, then restart.

My server stopped loading the file after an edit. Why?

Almost always a JSON mistake, such as a missing or extra comma. Run the file through the DayZ File Checker to find the line.

Is it the same file on console and PC?

Yes, the format is the same on every platform.
