MasterBuilderHeeler
Precision building tools for Valheim: pitch, yaw, and roll rotation, grid snapping, piece nudging, ghost freeze, in-place piece moving, piece sampling, build camera, and build info panels.MasterBuilderHeeler
In native Valheim, piece placement is limited to single-axis rotation in fixed steps from the player's viewpoint, with no way to tilt pieces, nudge placement offsets, align to a build grid, or reposition placed pieces without dismantling them. MasterBuilderHeeler adds 3-axis rotation, step scaling, piece nudging, ghost freezing, grid snapping, in-place piece editing, piece sampling, a tethered Build Camera, and HUD info panels.
Placed and edited pieces use standard Valheim network data, so the mod works in single-player and on unmodded multiplayer servers. When installed on a server, gameplay and reach rules can be synchronized across connected players.
Acknowledgements
MasterBuilderHeeler draws inspiration from the following Valheim mods and community members. Perfect Placement and Build Camera Custom Hammers Edition were probably the biggest in this regard because they were separate mods built on older foundations, not designed to specifically work together, and very notably, also no longer broadly available on modding platforms. This mod was written to bring precision placement and free-camera building together in a single, widely available, up-to-date mod for the community.
- Perfect Placement: Standalone placement mod extracted from ValheimPlus and maintained as a standalone mod by Azumatt, no longer available on widely used modding platforms.
- Build Camera Custom Hammers Edition: Originally created as Build Camera by gittywithexcitement and CookieMilk, updated by Vapok, and more recently maintained by Azumatt, no longer available on widely used modding platforms.
- ComfyGizmo: Created by Bruce (ComfyMods). A widely used, respected community standard for 3-axis gizmo rotation with a focused feature set. If you only want gizmo functionality, you should use their mod ComfyGizmo on Thunderstore, it's great!
- EulersRuler: Created by redseiko (ComfyMods), with appreciation for sharing ideas and inspiring the hover piece inspection panels. If you only need the hover/placement panels, you should definitely grab their very nice and lightweight mod, EulersRuler on Thunderstore.
- Searica: Thank you for the encouragement and inspiration to put this project together. You can see all of their wonderful mods on Searica's Thunderstore page.
Features
- 3-axis rotation: Rotate pieces across yaw, pitch, and roll in World or Local frames with a 3D ring gizmo, plus Corner Roof alignment for 45-degree roof slopes. Terrain tool pieces keep native rotation.
- Step presets and scaling: Switch between Fine, Standard, and Coarse rotation and nudge steps, and scale step sizes up or down on the fly.
- Ghost freeze and piece nudging: Pin the placement ghost in place to inspect alignment from any angle, and nudge pieces along Local or World axes.
- Grid snapping and overlay: Snap piece pivots or manual snap points to a configurable World or piece-anchored Local grid, with an optional terrain-following or flat grid overlay.
- In-place piece editing: Move and rotate already-placed pieces without dismantling them while preserving container contents, sign text, item stand attachments, portal tags, health, and structural support. Honors ward access, no-build zones, and crafting station rules. The piece must be in the equipped tool's build menu, and containers stay locked during an edit.
- Placement rules: Snapped, nudged, frozen, and edited pieces skip the base game rules for wood surfaces, floors, ceilings, non-supporting pieces, and required connections. Ward, no-build zone, and clipping checks still apply, and unsupported pieces still break.
- Piece and rotation sampling: Select the aimed piece directly in the Hammer build menu or copy a placed piece's 3D rotation onto the active ghost.
PrecisionCopyBehaviorsets how the sample keys work with native Copy Piece. - Build reach:
EnableExtendedAvatarReachextends player placement, repair, dismantle, and in-place edit reach toMaxBuildReachDistance.ValidateStationRangeAtPieceLocationchecks crafting station range at the target piece instead of the player. Both are off by default. The Build Camera always checks station range at the target piece. - Build Camera: Free-flying camera tethered to the player while holding a build tool, with an optional spotlight, Wisplight-gated Mistlands mist clearing, and nearby item auto-pickup gated by active Comfort, ward access, carry weight, and inventory space.
- HUD info panels: Optional on-screen control panels and piece inspection readouts showing active bindings, piece name, prefab ID, health, structural stability, rotation, distance, and world coordinates.
- Feature toggles: Turn off whole features, for example to keep only the Build Camera.
EnablePrecision,EnableBuildCamera,EnableGrid, andEnableInfoPanelsremove the feature, its keys, and its HUD rows, and apply live without a restart.
Configuration
[!NOTE] Gamepad bindings are not available yet for this mod. Gamepad configuration is coming soon.
Settings, keybindings, panel positions, and theme colors can be changed live using the BepInEx Configuration Manager or by editing BepInEx/config/dreamwraith.MasterBuilderHeeler.cfg. The mod reloads the file when it is saved, without a restart:

Client | Color and opacity settings for 3D gizmo rings and arrows, HUD text roles, status indicators, and health/stability gradients. |
Sync policies: Client settings are never synced and stay under each player's control. Server and Conditional (Server) settings are server-controlled by default, and administrators can defer them to clients. Conditional (Client) settings are client-controlled by default, and administrators can enforce them. A section with more than one policy contains settings of each listed type. LockConfiguration keeps server-controlled settings editable by server administrators only.
Keybindings: All mod actions can be rebound in the Keybindings (Keyboard & Mouse) section. While a build tool is equipped, the Global panel shows the active bindings. The Precision panel shows its bindings while Precision Mode is on.
[!NOTE] Default keyboard bindings avoid native Build Mode controls and BepInEx Configuration Manager (
F1), whileZ,B,K, andLoverlap with Valheimdebugmodeshortcuts (ToggleDebugFly,ToggleNoPlacementCost,killenemies, andremovedrops). Players who regularly build withdebugmodeenabled should rebind those keys in Configuration Manager.
Compatibility
- Multiplayer and single-player: Works in local worlds and on multiplayer servers, including servers that do not have the mod installed.
- Optional server sync: When installed on a server with ConditionalConfigSync, administrators can enforce feature toggles, reach, Build Camera limits, Mistlands mist clearing, and auto-pickup rules while leaving keybindings, colors, camera feel, and HUD layout under each player's control. Feature toggles are server-controlled by default, and administrators can defer any of them to clients. Policies can be customized in
ConditionalConfigSync.SyncPolicy.cfg. - Input devices: Keyboard and mouse controls are supported for mod actions. Gamepad shortcuts for mod actions are not yet implemented, though native gamepad building continues to work. Sorry, I will get gamepad added very soon. Maybe next release.
- Mod managers: Compatible with Gale, Thunderstore Mod Manager, and r2modman.
Compatible Mods
Tested with MasterBuilderHeeler:
Incompatible Mods
MasterBuilderHeeler does not load when either of these mods is installed. Check the BepInEx log if the mod does not start:
- Perfect Placement: Overlaps placement, rotation, in-place editing, and grid alignment.
- Build Camera Custom Hammers Edition: Overlaps the Build Camera.
Overlapping Mods
These mods overlap with parts of MasterBuilderHeeler. Do not run the overlapping features together. Each mod should work if the listed feature is off, but these combinations are not tested:
- ComfyGizmo: Overlaps 3-axis rotation and the gizmo. Set
EnablePrecisionto off. - EulersRuler: Overlaps the Hover and Placement panels. Set
ShowPanelto off inHover PanelandPlacement Panel, or setEnableInfoPanelsto off to remove all panels.
On a server with the mod installed, the Enable settings are server-controlled by default, so an administrator must change them or defer them to clients.
Installation
Mod Manager (Recommended)
Install through Gale, Thunderstore Mod Manager, or r2modman. Dependencies are installed automatically.
Manual Installation
- Install BepInExPack Valheim, Jotunn, and ConditionalConfigSync.
- Download the latest release from GitHub, Thunderstore, or Nexus Mods
- Place
MasterBuilderHeeler.dllintoValheim/BepInEx/plugins/. - Launch Valheim.
Server Installation (Optional)
A server install is not required. To enforce settings across connected players, install BepInExPack Valheim, Jotunn, ConditionalConfigSync, and MasterBuilderHeeler on the server. Clients need ConditionalConfigSync with or without a server install.
On a headless dedicated server, the mod loads its settings for sync only. It applies no patches and runs no input, HUD, or rendering code. Saved changes to the server config file reload and sync to connected players without a restart.

Building from Source
Build using the .NET SDK:
dotnet build MasterBuilderHeeler.sln -c Release
The compiled assembly is output to bin/Release/net48/MasterBuilderHeeler.dll. Building with the Release configuration also creates a distribution zip in bin/Publish/.
The build references ConditionalConfigSync.dll from BEPINEX_PATH. Install ConditionalConfigSync in plugins/ or plugins/shudnal-ConditionalConfigSync/ under that folder before building.
Custom & CI Paths
For custom installations, non-standard Steam paths, or mod manager profiles, copy Environment.props.example to Environment.props in the project root to configure your paths:
VALHEIM_INSTALL: Root Valheim installation folder.BEPINEX_PATH: Root BepInEx folder (containingcore,plugins, etc.).
Alternatively, you can set VALHEIM_INSTALL and BEPINEX_PATH as environment variables.
Packaging and Releases
Packaging and release automation are handled through .scripts/modtools.ps1 using the DW.ValheimModTools module:
- Create a release:
pwsh ./.scripts/modtools.ps1 release(builds Release, creates distribution archives, extracts changelog notes, and creates a GitHub Release). - Bump version and package:
pwsh ./.scripts/modtools.ps1 package -Bump Patch - Publish to mod portals:
pwsh ./.scripts/modtools.ps1 publish -Target All(uploads to Thunderstore and Nexus Mods).
