UE Quick Menu

The Quick Menu lets you invoke AI operations directly within the Unreal Engine Editor — no need to switch to the NexusFlow sidebar to type a request.

Overview

NexusFlow provides four entry points in the UE Editor, offering a total of 17 AI operations:

Entry PointLocationOperations
Blueprint Editor Right-ClickRight-click in the Blueprint graph13 operations
Content Browser Right-ClickRight-click on Blueprint assets2 operations
Blueprint Editor ToolbarToolbar inside the Blueprint Editor2 operations
Level Editor ToolbarMain editor toolbar (NexusFlow button)Connection status + quick access

When you select an operation, NexusFlow automatically:

  1. Opens the sidebar (if hidden) and focuses the chat input
  2. Sends the preset prompt with full Blueprint context
  3. Displays the AI response in the sidebar

TIP

If the AI is currently processing a request, the Quick Menu will show a toast notification and discard the new prompt to avoid conflicts.

Blueprint Editor Right-Click Menu

Open a Blueprint, optionally select one or more nodes, then right-click in the graph area. The NexusFlow submenu appears with operations filtered by your selection.

Selection Mode

Each operation has a selection mode that controls when it appears in the menu:

ModeMeaningExample

Content Browser Right-Click Menu

In the Content Browser, right-click on one or more Blueprint assets to access NexusFlow operations at the asset level.

OperationSelectionDescription
Explain BlueprintanyAnalyze the overall structure and purpose of a Blueprint
Document BlueprintanyGenerate comprehensive documentation for a Blueprint

INFO

These operations work on the entire Blueprint asset, not individual nodes. They're ideal for getting a high-level understanding of Blueprints you didn't write.

Blueprint Editor Toolbar

When a Blueprint is open in the editor, two buttons appear in the Blueprint Editor toolbar (top bar):

OperationDescription
Review BlueprintPerform a quality review of the current Blueprint (structure, naming, best practices)
Summarize BlueprintGenerate a concise summary of what the Blueprint does

These toolbar buttons are always visible — they don't depend on node selection.

Level Editor Toolbar

The NexusFlow button in the Level Editor main toolbar provides quick access and connection status at a glance.

Connection Status

The button icon changes based on whether the NexusFlow desktop app is running:

StatusIconClick Behavior
ConnectedColor iconOpens the sidebar and focuses chat input
Not ConnectedGray iconShows a notification with download links

Not-Connected Notification

When NexusFlow is not running, clicking the toolbar button displays a notification popup with:

  • A message explaining that the NexusFlow desktop app is required
  • GitHub download link — latest release page
  • Mirror download link — accelerated download for users in China

WARNING

The Level Editor toolbar button is a quick-access shortcut, not an AI operation trigger. To use AI operations, go through the Blueprint Editor right-click menu, Content Browser right-click menu, or Blueprint Editor toolbar.

Language Support

Quick Menu item names are displayed in the UE Editor's language setting:

LanguageExample
EnglishExplain Graph
简体中文解释图表
繁體中文解釋圖表

The language is determined by UE's locale, not the NexusFlow app's language setting.

Context Information

When a Quick Menu operation is triggered, the following context is automatically collected and sent to the AI:

  • Blueprint Asset Path — The location of the current Blueprint in the project
  • Graph Name — The graph currently being edited (e.g., EventGraph, a function graph)
  • Selected Node IDs — All currently selected Blueprint nodes (if any)
  • Extension Point — Which menu triggered the operation

WARNING

The Quick Menu requires the NexusFlow desktop app to be running and connected to UE. If the connection is lost, menu items will still appear but operations won't be sent.
