DataForge reads vanilla content and content registered by your installed mods.

Global settings

| Setting | Default | What it does |

| --- | --- | --- |

| Stackable Stack Multiplier | 1 | Multiply stack sizes by 1–10. An item's explicit maxStackSize takes priority. |

| Item Weight Multiplier | 1 | Multiply item weights by 0–2. An item's explicit weight takes priority. |

| Upgrade Material Scaling | Vanilla | For a base cost of 10, qualities 2/3/4 cost 10/20/30. Flat gives 10/10/10; Reduced gives 10/15/20. Exact-quality costs stay as written. |

| Show Comfort In Hammer | On | Show comfort values and related comfort-group hints in the hammer menu. Client setting. |

| Highlight Station Extensions In Hammer | On | Highlight related stations and extensions on hover. Client setting. |

| Ignore Station Extension Spacing | On | Allow extensions to be placed close together. Other placement rules still apply. |

| Fireplace Fuel Multiplier | 10 | Multiply every finite, refillable fireplace's original fuel capacity, including the displayed maximum. 1 restores the original capacity. Existing fuel and burn speed stay unchanged. |

Fireplace Fuel Multiplier accepts whole numbers from 1 to 9999. At the default

10, a wood torch holds 40 fuel and a hearth holds 200. Changes always use each

fireplace's original capacity, so multipliers do not compound. Lowering the setting

does not delete stored fuel: it must burn below the new limit before you can add more.

This setting does not change smelters or cooking stations. AzuCraftyBoxes uses the

same capacity for nearby-container refuelling; DataForge also guards its reviewed

1.8.27 fill-all calculations against negative amounts when excess fuel remains.

The former maxStoredFuel and Fireplace Fuel Capacity settings are not read or

migrated. Set the new multiplier explicitly if you want a value other than 10.

Vanilla fireplaces return building materials on dismantling, but not their stored

fuel. With a multiplier above 1, DataForge also returns whole fuel units remaining

after subtracting the fireplace's starting fuel. For example, 50 fuel remaining

with 3 starting fuel returns 47. This also applies at multiplier 1 while stored

fuel still exceeds the restored capacity. Destruction with blocked drops returns none.

Start here

• Install DataForge and BepInExPack Valheim 5.4.2351. For multiplayer, install the same DataForge version on the server and every client.
• Start a world, or start your dedicated server and let its game data load.
• Open BepInEx/config/DataForge/ in that installation. If you use a mod manager, open the active profile's config folder.
• Find the entry you want in a reference file. Copy it into the matching edit file below.
• Keep the entry name, set override: true, and keep only the fields you want to change. Save the file. DataForge reloads supported changes automatically after a short delay.

In multiplayer, edit the host or dedicated server's files. Connected clients use the server's settings, not their own local YAML.

For a first edit, put this in items.yml to make Wood lighter and stack to 100:

• item: Wood

override: true

weight: 1

maxStackSize: 100
