MaterialsBoost

Fine-grained, per-resource yield multipliers for mining nodes and trees in Valheim. Scale specific ores and woods individually — no blanket loot scaling, no changes to creature drops, chests, or pickables.

Built for Valheim 1.0 and BepInEx.

What it does

• Discovers every mineable and choppable resource drop at world load
• Generates one config entry per discovered item, so you can set exact multipliers per resource
• Only touches drops from mining nodes and trees — nothing else in the loot system is affected
• Server-authoritative: on multiplayer, the server's values are what count

Configuration

Config file:

BepInEx/config/jaredcavanagh.materialsboost.cfg

Every discovered mining and chopping drop appears automatically after the first load. Entries are integers; 1 keeps the vanilla amount.

[MiningYieldMultipliers]

## Yield multiplier for 'CopperOre' when mining ore/rock nodes. 1 keeps the vanilla amount; set higher to increase the drop.
# Setting type: Int32
# Default value: 1
CopperOre = 2

[ChoppingYieldMultipliers]

## Yield multiplier for 'Wood' when chopping trees. 1 keeps the vanilla amount; set higher to increase the drop.
# Setting type: Int32
# Default value: 1
Wood = 4

Multipliers are applied against the captured vanilla values, so editing the config live (via an in-game config manager) re-applies cleanly without compounding. No world restart required.

Sources covered

Drops from MineRock, MineRock5, TreeBase, and TreeLog — e.g. CopperOre, TinOre, IronScrap, SilverOre, Stone, Wood, FineWood, RoundLog (core wood), Resin, and any other item those sources drop.

Multiplayer

Install on the server for authoritative behavior. As of v1.1.0, MaterialsBoost uses ServerSync:

• The server pushes its multipliers to connected clients automatically — clients that also have the mod display and use the server's values (no manual config matching).
• Clients without the mod can still connect (ModRequired = false).
• General > LockConfiguration (default on) means only server admins can change the synced multipliers; other players can't override them.

Edit multipliers in the server's config, then restart the server. Single-player works normally.

Note: Valheim 1.0 disables crossplay when mods are present — this applies to all BepInEx mods, not just this one.

Changelog

1.1.0 — Added ServerSync: the server now syncs multipliers to clients, with an admin LockConfiguration option. Clients without the mod can still connect.

1.0.0 — Initial release for Valheim 1.0.

Credits

MaterialsBoost is an independent reimplementation written from scratch for Valheim 1.0. It was inspired by the discontinued ResourceBoost mod by CalebHanson95, whose repository is no longer available and which no longer loads on Valheim 1.0. No original code or assets from that mod are included here. Thanks to CalebHanson95 for the original concept.
