SaveStructure

SaveStructure

Build it once. Save it. Build it again.

SaveStructure lets you select building pieces with your Hammer, name the structure, and rebuild it from the Hammer menu. Build the whole layout at once, or place a local hologram and construct it one piece at a time.

Features

• Select individual pieces with visible outlines; click again to deselect.
• Select a box covering multiple floors, then fine-tune the selection individually.
• Copy supported buildable pieces from ruins and other players' buildings, subject to ward access.
• Save named structures and find them immediately in the Hammer menu.
• Use readable save filenames and automatic short suffixes when names clash.
• Delete saved blueprints or unfinished holograms in-game, with confirmation.
• Preview the whole structure, rotate it, and use its snap points for placement.
• Build the complete layout using its total material cost.
• Place a free hologram visible only to you, then build each piece using its full material cost.
• Resume unfinished holograms after reconnecting to the same world with the same character.
• Toggle placement overlap checks and configure every mod shortcut, including modifiers and mouse buttons.
• Keep your saved structures across restarts and use them in other worlds.
• Rebuild ordinary pieces that can be repaired and dismantled normally.
• Respect extended Hammer reach and placement input supplied by compatible build-camera mods.
• Use native material checks and consumption so compatible chest-pulling mods can supply whole builds and hologram pieces.

Requirements and installation

Built against Valheim 1.0.16, with BepInExPack Valheim 5.4.2350. Jötunn is not required.

With a mod manager: install SaveStructure and its listed dependency, then launch your modded profile.

Manual installation: close Valheim and extract the package into BepInEx/plugins/SaveStructure/ in your active installation or mod profile. SaveStructure.dll should sit directly inside that folder. Launch the game through that profile.

How to save a structure

• Equip your Hammer and press F8 to enter save mode.
• Aim at a supported Hammer piece and left-click to select it. A mint outline marks selected pieces. Click a selected piece again to remove it from the selection. Buildable ruin pieces and other players' pieces are eligible; protected wards still restrict access.
• Select the rest of the pieces you want to save. Start with a foundation or floor piece: the first selected piece defines the placement anchor and facing.
• Press F7, enter a name, and confirm the dialog. The Hammer entry uses your chosen name. If it already exists, a short suffix is added automatically, for example Cabin [a3f91c].

Normal hammer placement, repair and removal are blocked while save mode is active.

For box selection, hold Left Shift and right-click while in save mode. Click a lower corner of the area, aim at the opposite corner, then click again to confirm. Scroll up / down to increase / decrease the height above the corners. While in box-selection mode, scrolling adjusts height without also zooming the camera or rotating a piece. The box includes pieces whose placement pivots fall inside it. Check the highlighted candidates before confirming; over-limit boxes are rejected without partially selecting them.

Additional boxes add to your selection. Left Shift + right-click again to add or remove individual pieces. If the selection was empty, the lowest piece nearest the first box corner becomes the anchor. If you select a piece individually first, that anchor is retained.
