Runic Precision Build Tool

Build beyond the grid without abandoning Valheim's building system.

Runic Precision Build Tool adds precise three-axis rotation and world-axis positioning to the vanilla hammer workflow. Rotate beams into ornamental patterns, form complex roof lines, recess lights into stone, or make tiny alignment corrections—all while retaining Valheim's familiar placement preview and snapping behavior.

Features

• Pitch and roll any rotatable build piece in addition to vanilla yaw.
• Move the placement ghost along fixed world X, Y, and Z axes.
• Normal and fine adjustment steps for both rotation and movement.
• Preserve transformed snap points while rotating pieces.
• Deliberately inset pieces into other geometry for detailed construction.
• Toggleable RGB orientation rings show the piece's local axes and the fixed world planes.
• Optional controls appear inside Valheim's native bottom build-hint strip.
• Reset the current placement state without reopening the hammer menu.
• Client-side operation with no custom data added to placed pieces or world saves.
• No Jotunn dependency.

Controls

Control	Action
Mouse wheel	Vanilla yaw rotation
Left Alt + Wheel	Pitch around the piece's current local axis
Left Alt + Left Shift + Wheel	Roll/twist around the piece's current local axis
Left Alt + Left/Right Arrow	Move along world X
Left Alt + Up/Down Arrow	Move along world Y
Left Alt + Page Up/Page Down	Move along world Z
Hold V while adjusting	Use the fine step
Left Alt + R	Reset rotation, yaw, movement offset, and snap selection
G	Toggle the 3D guides and expanded native control hints

Bright red, green, and blue rings represent the object's current local X, Y, and Z axes. The larger translucent rings remain aligned to the world, making the object's orientation easy to read.

Installation

Mod manager

Install through Thunderstore Mod Manager or r2modman. The required BepInEx pack will be resolved automatically.

Manual

1. Install BepInExPack Valheim.
2. Place RunicPrecisionBuildTool.dll in BepInEx/plugins/RunicPrecisionBuildTool/.
3. Start Valheim.

Configuration

After the first launch, configuration is written to:

BepInEx/config/chazman.RunicPrecisionBuildTool.cfg

The normal and fine rotation steps, normal and fine movement distances, control modifiers, and general enable state can be changed there. The default fine modifier is V; this mod deliberately does not use Ctrl so it can coexist with build-camera controls.

Multiplayer and compatibility

Runic Precision Build Tool is client-side. A dedicated server and other players do not normally need the mod because Valheim already synchronizes the final position and quaternion of a placed piece.

The mod does not add custom components or metadata to placed pieces and does not change the world save format. Removing it leaves already placed pieces intact. Servers with restrictive mod policies or server-side placement validation may still prohibit or reject unusual placements.

The tool avoids globally consuming inputs and leaves ordinary building unchanged unless its modifier keys are held. If another mod uses the same shortcuts, change that mod's bindings or the available Runic Precision configuration entries.
