Installation

How to install the Blueprint AI Assistant plugin in your Unreal Engine project.

For the full AI integration reference (HTTP server, batching, all verbs), see AI Guide.

Prerequisites#

  • Unreal Engine 5.7 or later
  • Windows (Win64) only. Other platforms are not currently supported.
  • Visual Studio 2022 or Rider (for building C++ plugins)

Optional dependencies#

Some verb categories are optional and require their respective engine plugins to be enabled:

  • EnhancedInput: verbs for InputAction and InputMappingContext assets
  • Niagara: verbs for NiagaraSystem and NiagaraEmitter assets

If these plugins are not present, the corresponding verbs will not be registered. All other verbs work without additional dependencies.

Install from Fab#

  1. Purchase or download Blueprint AI Assistant from Fab.
  2. In the Epic Games Launcher, add the plugin to your project.
  3. Open the Unreal Editor. The plugin is auto-enabled on first launch.

Install from Source#

  1. Download or clone the plugin repository.
  2. Copy the BlueprintAIAssistant folder into your project's Plugins/ directory.
  3. Your project structure should look like:
YourProject/
  Plugins/
    BlueprintAIAssistant/
      BlueprintAIAssistant.uplugin
      Source/
      ...
  YourProject.uproject
  1. Right-click your .uproject file and select "Generate Visual Studio project files" (or the Rider equivalent).
  2. Build the project (Build > Build Solution, or F5 in your IDE).
  3. Open the Unreal Editor.

Verifying Installation#

  1. In the editor, go to Edit > Plugins and search for "Blueprint AI Assistant". It should appear and show as enabled.
  2. In the Content Browser, right-click any Blueprint asset. You should see a "Blueprint AI Assistant" entry in the context menu.
  3. From the command line, run a test command:
UnrealEditor-Cmd.exe YourProject.uproject -run=BlueprintAIAssistant -verb=help -nullrhi -nosplash -nosound -unattended

This should output JSON with a list of all available verbs.

Updating#

Replace the Plugins/BlueprintAIAssistant/ folder with the new version and rebuild. No project settings migration is needed. Settings are stored per-user and are compatible across versions.

Uninstalling#

  1. Delete the Plugins/BlueprintAIAssistant/ folder.
  2. Regenerate project files (right-click .uproject > "Generate Visual Studio project files").
  3. Rebuild the project.
