The Blueprint Architect is the main AI chat view. It is where you prompt the AI to generate, modify, and analyze Blueprints and assets.
Interaction Modes
Four modes control how the AI behaves. Switch between them using the buttons at the bottom of the chat:
Just Chat
The AI responds conversationally. No tools are executed. Good for asking questions, getting explanations, or planning before building.
Ask Before Edit
The AI proposes tool calls but waits for your confirmation before executing each one. You see a preview of what it wants to do and can approve, reject, or stop.
Auto Edit
The AI executes tools automatically without confirmation. This is the fastest mode for generation. Recommended once you trust the workflow.
Plan
The AI creates a step-by-step plan before executing. Good for complex multi-step tasks where you want to review the approach first.
How to Prompt
The AI understands natural language. You can be as vague or specific as you like:
- “Create a third person character with movement, health, and sprint”
- “Add a Niagara fire effect to the current folder”
- “Build a main menu widget with Play, Settings, and Quit buttons”
- “Create a behavior tree for an enemy that patrols and chases the player”
- “Generate a PBR material that looks like rusty metal”
Tips for Better Results
- Be specific about what you want. “Create a character” is fine, but “Create a third person character with Enhanced Input, a health system, sprint with stamina drain, and crouch” gives much better results.
- Reference existing assets using the @ mention system (type @ to search).
- Attach context with the File button to give the AI more information.
- Use the correct folder - the AI creates assets in the currently focused Content Browser folder. Navigate there first.
Tool Execution
When the AI executes tools, each one appears as a collapsible bubble in the chat showing:
- Tool name and action
- Success (green) or failure (red) indicator
- Click to expand and see the full result
The AI can execute multiple tools per response and chains them together to build complex systems.
@ Asset Mentions
Type @ in the chat input to search for any asset in your project. Selecting an asset adds it as context for the AI, so it can reference that specific Blueprint, Material, or other asset when responding.
File Attachments
Click the File button to attach source files (C++ headers, config files, text documents) as context. The AI reads the file content and uses it to inform its responses.
Image Attachments
Click the Image button or paste from clipboard to attach screenshots or reference images. The AI can analyze images to understand what you want to build.
Flowcharts
The AI generates visual flowcharts in responses to show Blueprint logic structure. These render as interactive SVG diagrams that you can:
- Click to expand in a larger window
- Export as PNG
- View the full node-connection architecture at a glance
Conversations
- Create multiple conversations with the New Chat button
- Switch between conversations from the sidebar
- Conversations persist across editor restarts
- Rename conversations by clicking the title
- Delete individual or all conversations
Token Counter
The token counter at the top shows estimated token usage for the current conversation, helping you track API costs.
