👀 Summary

Spyglass is a lightweight Unreal Engine editor plugin that builds an interactive graph showing how your plugins depend on one another. Hover a node to see detailed information, pan around the view and tweak layout forces to suit your preferences.

An example project: 13 Ns plugins and 11 engine plugins, with the dependencies from their .uplugin files. The graph uses the force layout and the highlight rules of the Spyglass tab. Point at a plugin to see what it depends on (bright lines) and what depends on it (dim lines). Drag a node or the space, and scroll or pinch to zoom. Changes from the editor: the view fits the graph until you pan or zoom, and the layout stops when the nodes are almost at rest.

📦 Features

Force-directed graph that visualises plugin dependencies.
Hover info panel describing authors, modules and references.
Customisable settings to tune repulsion and centering forces.

⚙️ Requirements

Unreal Engine 5.2 or newer and a C++ project that can compile plugins.

🛠️ Installation

Clone or download this repository.
Copy the NsSpyglass folder into your project’s Plugins directory. Create the Plugins folder if it does not exist.
Regenerate your project files so the engine can find the new plugin.
Open the Unreal Editor and enable NsSpyglass under Edit → Plugins then restart the editor.

🚀 Getting Started

Launch your Unreal Engine editor and navigate to Window → Spyglass → Plugin Dependency Viewer. The plugin scans your project and displays an interactive graph of all plugins and their relationships.

Navigating the Graph

Drag nodes to reposition them.
Scroll to zoom in and out.
Hover a node to see details such as modules, plugin location and referenced plugins.
Use the settings panel to adjust the repulsion and centering forces that control the layout.

Understanding Dependencies

Each node represents a plugin. Lines between nodes show that one plugin references another. Use this view to quickly spot missing references or circular dependencies.
