Techtonica VR Mod

This is a mod for the game Techtonica that adds VR support.

🔥 CAUTION
This mod is still in early development and will contain bugs. Use at your own risk. Only tested with the Valve Index / Pimax Crystal and Knuckles controllers.

Prerequisites

• Version 0.2.1c of the game. As the game is still in early access, this mod may not work with future versions of the game. If you encounter any issues, please create an Issue.
• BepInEx version BepInEx Version

Setup

You can install the mod from Thunderstore or install it manually:

BepInEx

1. Download the latest 5.x release of BepInEx from the Releases page.
2. Extract the downloaded archive into the game’s installation directory.
3. Run the game once. BepInEx should be installed automatically.

VR Mod

1. Download the latest release (v0.5.0) of this mod from the Releases page.
2. Extract the downloaded archive.
3. Copy the BepInEx and Techtonica_Data folders to the Techtonica folder in steamapps/common directory.
4. Run the game. The mod should be loaded automatically by BepInEx.

Audio Fix

Teleport and Snap turn have audio cues that are not played unless Tobey.UnityAudio is installed. You can install it from Thunderstore or the GitHub Releases page.

• The GitHub release of the VR mod includes the audio fix so you don’t need to install it separately.
• The thunderstore release does not include the audio fix unless you install it using a mod manager that installs dependencies.

To manually install the UnityAudio extract the BepInEx folder from the downloaded archive into the game’s installation directory.

Disabling the Mod

To disable the mod change the Enabled under [General] value in the de.xenira.techtonica.cfg file in the BepInEx/config folder to false.

Uninstalling the Mod

To uninstall the mod remove the mod’s files from the BepInEx/plugins folder. This should be the following files:

• techtonica_vr.dll
• 'techtonica_vr' folder

If you installed the audio fix, remove the BepInEx/patches/Tobey/UnityAudio and BepInEx/plugin/Tobey/UnityAudio folder from the game’s installation directory.

There will be some leftover files in the Techtonica_Data folder. To clean those up, delete the folder and verify the game’s files in Steam. This will redownload the game’s files and remove any leftover files. This is not strictly necessary but it will keep your game folder clean.

Current State

While the mod is in a playable state, it is still in early development. Some features are still missing and there are some known issues. Other things might be a little yanky or not work as expected.

Working

• Rendering of the game world with 6DOF Tracking
• Tracking of the player’s head and hands
• Smooth locomotion and turning
• Comfort options (Teleportation, Snap turning, Vignette)
• Basic controller bindings (Although they might not be optimal)
• Controller haptics
• Smooth turning
• UI

Missing

• Gesture support (e.g. Mining using pickaxe motion)
• Model for the player’s body. Currently not a priority as this requires IK.
• Default bindings for VR controllers other than the Valve Index Controllers (#16, #17)
• Object outlines. Disabled for now as the shader is broken in VR.
• Finger tracking (#15)
• Ability to switch primary hand
• Ability to yeet paladin down the waterfall
• Hand crank using uhhhhh... hands?

Known Issues

• Haptics are played on both controllers by the game. One improvement would be to play them on the hand that is actually holding the tool.
• The game is locked to 60fps when running in windowed mode. This is based on the refresh rate of your monitor. To unlock the framerate, switch to fullscreen mode. (#10)

Cool stuff to try

• Tobii eye tracking for dynamic foveated rendering
• Enable ik (The game ships with FinalIK so it should be possible. Probably just not networked yet.)

Configuration

The configuration file is located in BepInEx/config/de.xenira.techtonicavr.cfg. You can edit it using a text editor like Notepad.

Resetting the Configuration
