Frequently Asked Questions

How much does it cost to use the AI? Is there a free option?

The plugin is a one-time purchase on FAB. No subscriptions, no credits, no monthly fees.

For AI usage, you have several options:

• Free Built-In AI: The plugin ships with two free-tier slots that use real models. No API key required, no setup needed. Just open the plugin and start prompting. The most generous free AI usage offered by any UE5 copilot.
• Paid API Keys: Use OpenAI, Claude, DeepSeek, Gemini, OpenRouter, or any OpenAI-compatible endpoint. You pay the provider directly based on usage. 9 configurable API key slots with hotkey switching (ALT+1 through ALT+9).
• AI Agents: Run Claude Code, Codex, GitHub Copilot, or Gemini CLI directly inside the editor with full access to every tool.
• Local LLMs: Run entirely on your machine with zero internet required and complete privacy. Works with Ollama, LM Studio, Lemonade, and any OpenAI-compatible local server.

Is my code sent to external servers? Can I keep everything private?

You have full control:

• Cloud API Providers (Google/OpenAI/Claude/DeepSeek): Your prompts and context are sent to the AI provider for processing, standard for all AI tools.
• Local LLMs: Everything stays on your machine. Zero data sent anywhere. Perfect for sensitive projects. Works with Ollama, LM Studio, Lemonade, and any OpenAI-compatible server.
• AI Agents: When using CLI agents (Claude Code, Codex, etc.), data flows through the agent’s own API. Each agent has its own privacy policy.

How does this copilot compare to other AI plugins?

Scope. Other plugins handle a handful of tasks. This is an engine-wide copilot covering 56 tool categories:

• Generates full Blueprint logic, animation state machines, material graphs, Niagara VFX systems, UMG widget layouts, behavior trees, state trees, sequencer cinematics, PCG procedural worlds, and more from natural language.
• Analyzes your entire project for intelligent Q&A with interactive dependency graphs, pie charts, and flowcharts.
• Generates assets from text: textures, PBR materials, 3D models, sound effects, and voiceovers.
• Voice control: speak to the copilot, get spoken responses back.
• Runs 4 concurrent AI agents inside the editor (Claude Code, Codex, Copilot, Gemini).
• Built-in learning ecosystem with courses, skill tree, XP, achievements, and leaderboard.
• One-time payment. Full C++ source code. Free AI usage included. 20 languages supported. Works on Windows, Mac, and Linux.

Is this just for beginners? Or can experienced developers use it too?

Both. For beginners, it’s the ultimate learning tool. Select any node, material, or behavior tree and ask for an explanation. The built-in learning tab has courses, video tutorials, and a skill tree to guide your progress.

For experienced developers, it’s a massive productivity multiplier. Generate entire gameplay systems in minutes, scaffold complex UI layouts from a description, build cinematic sequences with camera rigs, create PCG scatter systems across landscapes, and automate tedious repetitive tasks so you can focus on what makes your game unique.

Do I need to know C++ to use this?

Not at all. The primary way to use the plugin is with plain English or your native language. The C++ tools (reading, editing, compiling source files) are entirely optional and designed for advanced users. The included source code for the plugin itself is for transparency and modification, not required to operate it.

Does this work in languages other than English?

Yes. The entire plugin UI supports 20 languages: English, Spanish, French, German, Chinese, Japanese, Russian, Portuguese, Korean, Italian, Arabic, Dutch, Turkish, Polish, Vietnamese, Indonesian, Hindi, Romanian, Thai, and Ukrainian.

You can write prompts in your native language and the AI will generate the correct Blueprint logic, materials, animations, and everything else. Think in your language, create in Unreal.

What AI providers are supported?

Cloud: OpenAI (GPT-4, GPT-4o, o1, o3), Claude (Sonnet, Opus, Haiku), Google Gemini (Flash, Pro), DeepSeek, and any model via OpenRouter.

Agents: Claude Code, OpenAI Codex, GitHub Copilot, and Google Gemini CLI run directly inside the editor.

Local: Any OpenAI-compatible local server including Ollama, LM Studio, and Lemonade.

Custom: Any endpoint that accepts the OpenAI chat completions format. Enter your URL and model name in the Custom provider dropdown.

Free: Two built-in free-tier slots, no API key needed.

What Unreal Engine versions are supported?

UE 5.5, 5.6, and 5.7. Windows, macOS, and Linux (Editor only).

What is your update and support policy?

Lifetime updates included. Your one-time purchase grants access to all future features and engine version support. AI prompt files and tool documentation update automatically from the cloud without requiring a plugin rebuild.

For support: join our Discord community for help from the dev and other users, or use the built-in Report button in the Architect view to send bug reports with screenshots and conversation context directly to us.

Can I use this with my existing projects?

Yes. The copilot works with any UE 5.5+ project. No migration or special setup required. Just enable the plugin, open the window, and start prompting.

What’s included in the C++ source?

Full source code for the entire plugin. Every tool, every manager, every UI component. Modify, extend, or learn from it. You own what you buy. No black box, total transparency.

Can I use this with MCP / Claude Desktop / external tools?

Yes. The plugin runs an MCP (Model Context Protocol) server on TCP port 9877. Claude Desktop, Claude Code, and any MCP-compatible client can connect and use all tools directly. A Claude Desktop extension manifest ships with the plugin.

I have an idea for a feature! Are you open to suggestions?

Absolutely. This tool is built for the community. Your feedback and feature requests directly shape the roadmap. Join the Discord and share your ideas. The best features often come from user suggestions.
