Let Valheim burn!
Makes all wood constructions and vegetation burnable. The fire will spread along connected burnables. Fire will cause damage to nearby not burnables.
Target (min) fps can be configured (default 30) to keep it still playable with larger buildings/bases burning. The fire quality will be adopted dynamically to meet the target fps (+-5).
Deactivate "Bloom" in your graphics settings (otherwise fire will be too bright).
Do not activate the FireHazard world modifier, except you want to starve.
Vanilla comparison:
Performance (FPS drops?)
If you experience fps drops even when nothing is on fire, check the following configurations: TargetFPS, NoSparks, EnvironmentalEffects, DungeonHandling, LocationHandling
How does fire start?
Fire extinguishes when
3 late game fire weapons: item_sword_eternal_flame, item_bomb_eternal_flame, item_arrow_eternal_flame
Upgrading from older version
If you are updating from a version prior 3.1.0 or adding this mod to an existing world, the locations won't be there as they are generated at world generation.
You can use the Upgrade World mod to generate the locations using the following console commands:
Dedicated Server Settings
Strongly recommended to use mods being capable of completely making structures invulerable when players are offline.

Only want fire spreading for some events?

How does fire start?
- each burnable has a basic fire health of 50 (configurable).
- lightning and fire damage will reduce the fire health until reaching 0 to ignite.
- trees cannot be ignited with normal weapons (though fire may spread to trees)
- increased fire spread likelihood during events
- the new eternal fire weapons will immediately set burnables on fire (also trees)
Fire extinguishes when
- piece is repaired with the hammer
- piece is hit by a craftable water bomb (item_bomb_water: 1 leather scraps).
- vegetation is hit the craftable water bomb
- hit by water (waves of the sea)
- heavy rain extinguishes fire
- piece and vegetation is hit by frost damage
- best option to stop a burning forest is to chop all surrounding trees, so the fire can not spread further

startDedicated Server Settings
Strongly recommended to use mods being capable of completely making structures invulerable when players are offline.
- MaxBurningPieces: set the maximum burning pieces per scene for players with no high end rig (~500)
- BurningPiecesDropCoal: set to materials, so materials are dropped once the piece is destroyed / or burning materials if you want to have more fun ;)
- or set StopBurningHealthPercentage to somewhere around 0.15, to not frustrate your players with loosing everything
- BurningVegetationDropCoal: set to coal or burning wood, so materials do not break progression
- BurningContainersDropCoal: set to materials, so materials are dropped once the container is destroyed / or burning materials if you want to have more fun ;)
- if you experience to heavy network load, deactivate WntSpawnVanillaFire and VegegationSpawnVanillaFire
- If your players have lower spec rigs:
- Disable EnvironmentalEffects
- Enable NoSparks
- Disable LocationHandling
- Disable DungeonHandling
High Performance Settings
- TargetFPS: set to very high framerate (500) to have lowest fire quality, thus having max FPS (though the automatic adoption of the quality according to framerate works quite decently).
- Enable PreLoadLocations to reduce jitter when moving from one zone to another (adds 20-60 seconds to startup time)
- Disable EnvironmentalEffects
- Enable NoSparks
- Disable LocationHandling
- Disable DungeonHandling
- BurningPiecesDropCoal: Nothing
- BurningVegetationDropCoal: Nothing
- BurningContainersDropCoal: Nothing
Cinematic Settings
- TargetFPS: set to 0 to always have highest quality; be warned, this may result in a slide show
- make sure you have active point lights and shadows active in your graphics settings
- ClutterDistance: increase clutter render distance up to ~150
- Enable EnvironmentalEffects
- BurningPiecesDropCoal: burning materials
- BurningVegetationDropCoal: burning materials
- BurningContainersDropCoal: burning materials
Event Settings (admin only mode)
Only want fire spreading for some events?
- set FireDamageCausesBurning to false, so only the eternal flame weapons cause burning
- set EternalFlameWeaponsCraftable to false, so only admins can spawn them
- set FireDamageCausesBurning to false
- set LightningDamageCausesBurning to false
- set SpreadFromFireplaces to false
- disable the events by adding any non-existing globkey to "Required GlobKey"
- empty EventImmediateFire
Compatibility:
- fully compatible with Krumpac mods
Playing with other mods adding locations?
- Add these locations to the NonBurnableLocations config, in order to hinder fire spread from contained fire sources
- The config must be set before the location is placed first;
- for existing worlds resetting trader locations using either VentureLocationReset or UpgradeWorld should fix burning locations
Client Configuration
- TargetFPS: fire quality will be reducued to reach at least target FPS (+-5)
- VisualDebug: visualize where the fire is going to spread to; for debugging only. Changing parameter during runtime will case artifacts
- ClutterDistance: by default clutter is only generated up to a distance of 45m. You can see the grass appear and disappear when you move. Increasing the clutter render distance may cause FPS drops.
- TintClutter: should the clutter become tinted (blass grass)
- NoSparks: Disable for lower spec rigs. Can have huge performance impact on lower spec rigs.
Server Configuration

- AdoptVanillaFire: adopts the vanilla fire to better fit with this mod (disabling is not adviced)

Otherwise fire will be added to locations at runtime, this may cause jitter when moving between zones. If disabled, locations will not be burnable after initial placement, but after reentering the zone. Can have impact on performance. Otherwise fire will be added to locations at runtime, this may cause jitter when moving between zones.
