Scene Compass

Overview

Scene Compass is a small, focused editor utility that replaces tape-measure GameObjects and "Viewpoint_v12" empties with two tools:

• a measure mode that draws distances between any two points in a scene with a single key,
• a bookmark system that saves viewpoints and GameObjects into named groups you can jump to from a hotkey.

There's no runtime component, no manager, no scene asset. Everything lives in EditorPrefs / ProjectSettings so it stays out of your builds.

Requirements

• Unity 2020.3 LTS or newer
• Editor-only — does not affect runtime, IL2CPP, or AOT platforms

Installation

Unity Asset Store

Scene Compass is free. Add it to your account, import via Package Manager, and the Window/Scene Compass menu appears.

UPM via Git URL

1. Open Window → Package Manager
2. Click the + menu → Add package from git URL…
3. Paste: https://github.com/simple-yet-efficient/scene-compass.git
4. Click Add

Manual .unitypackage

Download the latest release from GitHub Releases and import via Assets → Import Package → Custom Package….

Measure tool

Single measurement

• Hold M and hover over the scene view.
• Click once to set the start point, move the cursor, click again to set the end point.
• The distance is rendered as a floating label between the two points.

Multi-segment paths

• Hold Shift + M instead of just M.
• Every click adds a new segment. Release the modifier to finish.
• The total path length is shown alongside each segment length.

Snapping

Points snap to GameObject pivots by default. Hold Ctrl (Cmd on macOS) while clicking to snap to vertices instead.

Bookmark system

Save a viewpoint

Press Alt + Shift + B with the Scene view focused. A dialog appears:

• Name — the label shown in the Bookmarks window.
• Group — optional. Creates a new group if one doesn't exist.
• Type — Camera view saves position + rotation + FOV; GameObject saves a reference + framing offset.

Jump to a bookmark

Press Alt + B to open the Bookmarks window. Click any bookmark to teleport the Scene view camera. Double-click to also select the underlying GameObject.

Organise bookmarks

Drag between groups, rename with F2, delete with Del. Everything is stored per-project in ProjectSettings/SceneCompassBookmarks.json, so the data is under source control with the rest of the project.

Keyboard shortcuts

Shortcut	Action
M (hold)	Single-measurement mode
Shift + M (hold)	Multi-segment path mode
Alt + B	Open Bookmarks window
Alt + Shift + B	Add current view / selection as bookmark

Shortcuts are customisable via Edit → Shortcuts… under the Scene Compass category.

Project settings

Open Edit → Project Settings → Scene Compass to configure:

• Line colour and width for the measure tool
• Label font size and decimal precision
• Bookmark file path (defaults to ProjectSettings/)
• Auto-save on bookmark change toggle

Best practices

• Treat bookmarks as documentation. Naming a viewpoint "T-Junction — LOD bug repro" beats scribbling in a Notion doc.
• Group by task. One group per level, feature, or sprint keeps clutter manageable.
• Commit the JSON. Other team members get your bookmarks the moment they pull.

Troubleshooting

Symptom	Fix
Shortcut doesn't work	Another asset is grabbing M — check Edit → Shortcuts
Bookmark teleport looks wrong	FOV differs between bookmark and current Scene; re-save the view
Measure labels overlap	Reduce Label font size in Project Settings
