About this mod Author’s original text

PierSupports

Build bridges and piers without fighting to get supports down to the seabed.

Hold the extend key (Left Alt by default) while placing any vertical support (pole, pillar or column) and the mod stacks copies of that same piece straight down until it reaches the ground. That's it: no new pieces, no waterproofing, no other changes to building.

Features

  • Works with every vertical support: wood, core wood, darkwood, iron-reinforced, ashwood, timber, stone, black marble, Grausten and Flametal. Modded poles can be added by name.
  • Same piece, same cost: each added segment is a normal vanilla piece and costs its normal recipe. If you can't afford the full stack, nothing is added.
  • Real structural support: a stack that reaches the ground gives full grounded support, however deep the water. Break a segment out of the middle and the pieces above fall back to vanilla support rules.
  • Water or land: extends down to the seabed or to dry ground (cliffs, ravines). Can be limited to water only.
  • Vanilla wear: submerged pieces weather like any other; nothing is made waterproof.

Usage

  • Build out from shore or an existing structure.
  • Hold the extend key and snap a pole underneath (e.g. to the edge of a floor).
  • The pole stacks down to the ground and the message shows how many segments were added.

Poles still need something to snap to; vanilla does not allow placing pieces directly on the water surface.

Configuration

BepInEx/config/squatch.piersupports.cfg (or your mod manager's config editor):

| Setting | Default | Description |

|---|---|---|

| ExtendKey | LeftAlt | Any Unity key name: LeftControl, RightAlt, Mouse3, Mouse4, Z,... |

| MaxDepth | 32 | Max meters a stack will extend (guards against misclicks) |

| RequireWater | false | true = only extend when the ground below is underwater |

| ForceGroundedSupport | true | Full support for stacks that reach the ground |

| IncludePatterns | pole,pillar,column | Pieces that can be extended (* wildcards) |

| ExcludePatterns | props, arches, horizontal beams, tapered pillars | Pieces to skip |

Run pier_reload in the F5 console after editing the file.

Console commands

  • pier_list: every pole/pillar/column piece and whether it's eligible
  • pier_depth: ground height and water depth under you
  • pier_reload: reload the config

Multiplayer

Client-side. The server does not need it.

Anyone who builds piers needs the mod. Every player who plays near deep piers should also have it: Valheim calculates structural support on whichever client owns that area, and a client without the mod uses vanilla rules, which can damage tall stacks. Shallow piers are fine either way. Players without the mod can still join and see piers as normal pieces.

Removing the mod leaves every pier standing as regular vanilla pieces.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
