MaterialsBoost
Per-resource yield multipliers for mining nodes and trees, with server-to-client config sync. Scale individual ores and woods without blanket loot scaling.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
- Multiplayer: install on the server and each client; the server syncs its multipliers to clients automatically (see Multiplayer below)
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
The mod must be installed on the server and on every client that should get boosted drops. This is a Valheim limitation, not a choice: when a player mines or chops, that player's own game spawns the drops from its local drop tables, so the boost only applies if that client is running the mod. A player on a vanilla client can still connect, but their mining and chopping will yield vanilla amounts.
What clients do not need to do is configure anything. As of v1.1.0, MaterialsBoost uses ServerSync:
- The server pushes its multipliers to every connected client that has the mod — clients use the server's values, with no manual config matching.
- Clients without the mod can still connect (
ModRequired = false); they simply won't receive boosted drops from their own harvesting. General > LockConfiguration(default on) means only server admins can change the synced multipliers; other players can't override them.
So the recommended setup is to distribute the mod to your players (a shared modpack makes this one click) and configure everything on the server. Edit multipliers in the server's config and restart the server, or change them live in-game as an admin (requires an in-game config editor such as ConfigurationManager). 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
1.1.1 — Documentation fix: clarified that the mod must be installed on each client to boost that player's harvesting (a Valheim limitation). No code change — the plugin is unchanged from 1.1.0, so no client update is required.
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.
