Echolocation
Sound-driven echolocation or automatic 360-degree sonar every half second for BONELAB PCVR, with black vision, adjustable dots and optional Fusion player detection.Echolocation
See BONELAB through sound or repeating sonar scans. Black vision fills with fading dots on nearby surfaces.
For Windows PCVR with MelonLoader and BoneLib. Fusion is optional. This package is not a standalone Quest build.
Install
Close BONELAB, then copy Mods/Echolocation.dll into your game's Mods folder. Replace the old DLL and keep only one copy. You can also install the ZIP through a compatible mod manager.
Controls
Open BoneMenu > Echolocation.
- Scan Mode: Sound: dots react to walking, microphone and nearby sounds. This is the default.
- Scan Mode: Sonar: scan all around you every 0.5 seconds, even in silence. Scans pause while a menu is open.
- Send Pulse: reveal nearby surfaces. Desktop shortcut: F5.
- Enabled: toggle the mod. Desktop shortcut: F6.
- Double Clap: 360 Pulse: clap your empty hands together twice, separating them between contacts.
- Hold both index triggers for 1.5 seconds with empty hands to toggle black vision.
- Sound Inputs: control walking, microphone, game sounds and Fusion voice.
- Sonar Visuals: change dot size, brightness, range and ray limits.
- Clap and Pulse Sounds: toggle the sonar ping and clap feedback.
Remote players
Detected players appear green when visible and red behind cover. Both modes use the same walking, sound and optional proximity rules for players. Sonar alone does not reveal a silent, stationary player.
Remote Walking Detection (Even Without Audio) is on by default. It detects another player's grounded movement even when Fusion plays no footstep sound. Keep Walking and Landing on too. Standing still, head movement and your own walking do not count as their footsteps.
Turn off Remote Walking Detection for audio-only reveals. Remote Footstep Sensitivity adjusts detection of actual footstep audio; it does not affect the movement detector.
Faint Nearby Players optionally shows quiet people within a small radius. Turn it off when testing walking detection. After detected movement or sound stops, the stronger silhouette fades within half a second.
Notes
- Hearing and reveal ranges reach 3000 m, but loaded geometry, camera limits and actual audio playback still matter.
- Keep Optimize Walking and Sound Echoes on to reduce overlapping dots.
- Opening the quick menu restores normal vision so you can read controls.
- Effects stay local. Other players do not need Echolocation, and it sends no extra network messages.
- Custom avatars and unusual physics can need further fixes. Invalid avatar snapshots use a small head marker instead of an oversized silhouette.
- Use Print Input Levels to Console when reporting detection problems.
Version 1.9.0 adds Sound and Sonar modes. Repeating scans use bounded work and refresh nearby dots to reduce buildup. Native VR and multiplayer behavior still need in-game verification.
