If you feel like supporting this project, thank you kindly in advance!

If you don't, plague be upon you, your dog, your dog's brother, your dog's brother's cousin.. wait, no. Just enjoy the mod, and please do share your cool underground buildings with the world. The mod is free and always will be.

Features

image

This mod lets you dig proper caves, and create cliffs/overhangs/terrain arches and bridges just about anywhere.

How? It replaces Valheim's terrain engine with a voxel-based system.

  • Building inside caves is supported.
  • Viking make fire! Fire good! Even inside caves, fire good. Fire in your caves is supported.
  • Don't try to hide from mobs inside your little chicken cave. They'll find you (sometimes). Pathing inside caves is supported.
  • Multiplayer is supported - all players and the server itself will need to have this mod installed.

ALPHA VERSION - BE CAREFUL

This is a big mod that re-writes a lot of things. You are about to play the very first public version of it.

Please expect THERE WILL BE BUGS:

  • If you are using this with an existing savegame, make a BACKUP of your save before you run this mod.
  • During the early days of this mod in particular, there is an absolute chance a savegame may get corrupted, or future versions need to change in a way that isn't compatible with prior savegames

In short: While the mod is still young, please plan for any savegame you are playing on to be disposable in case of issues.

If you encounter bugs, I'd appreciate if you could report them in the Voxheim Discord's Bug channel.

Cave building 101

  • You can use your pickaxe to dig caves. Carving out terrain will now no longer remove all the upper terrain layers anymore.
  • The Hoe is your real weapon of choice, however.
  • By default, your hoe now has 6 upgrade levels
  • Starting from level 4, it will give you a new "Carve" ability to remove spherical terrain
  • Starting from level 5, it will give you a new "Add" ability to add spherical terrain
  • Higher hoe levels increase the maximum radius of your carve and add abilities

This mod is highly configurable - use your BepInEx config manager of choice.

Configurability

This mod is highly configurable. Among many other things, use your favorite BepInEx config manager to change:

  • How many hoe levels there are, and what their upgrade requirements are
  • At which levels you're getting the carve and add abilities, respectively
  • What their maximum radius should be for each level
  • Stamina usage
  • Resource usage

... and much more.

Installation

Ideally, use a plugin manager to install the mod and all dependencies.

If you'd rather do it manually, install the following dependencies:

Then, extract all contents within the 'plugins' folder of your zip file into <Valheim installation directory>\BepInEx\plugins\Voxheim.

When done, your Valheim game directory should contain BepInEx\plugins\Voxheim\Voxheim.Core.dll and BepInEx\plugins\Voxheim\Voxheim.dll.

Compatibility

Voxheim is compatible with the 1.0 Update - the Deep North.

Patch 0.1.10

Thanks to all of the Valheim community for giving this mod a whirl, and reporting bugs on the Voxheim Discord!

Many thanks to Adam, Marius and Yuki, the mod's first official Patreon supporters — may your caves shelter you from the strongest snowstorms! Your support is very much appreciated.

Version 0.1.10

  • Steep mountainsides no longer turn into stairs when you dig nearby
  • Voxel terrain steeper than 45° used to be built from flat steps and vertical walls. It follows the slope smoothly now
  • On existing worlds, spots you already dug into with an earlier version may keep some of the old steps right around the dig
  • Fixed distant terrain showing up inside caves
  • Fixed flat cave ceilings (e.g. carved with the Cube brush) and the flat undersides of torn chunks rendering pitch black
  • Improved compatibility with mods that recolor the terrain, such as "Seasons"
