ANSWERS FOR YOUR FIRST SESSION
AI Digital Human Lab gameplay guide and player questions
Steam edition · Researched Nov 11, 2026 · Guide updated Nov 11, 2026.
Our guidance
How can I start a conversation with Luna?
You can interact with Luna directly on your PC using either voice or text. Simply ask a question, share a story, or talk about your day. She responds in real-time with her own voice, accurate lip-sync, and expressive gestures.
Does this software require an internet connection for the AI to function?
No, the AI model and voice run locally on your own graphics card. This ensures your conversations remain private on your PC, requiring no subscriptions or API keys to operate the built-in AI features.
How do I connect an external AI assistant using MCP?
Click the robot button in the chat bar or type /mcp bind. Scan the QR code with your phone and send a message to your agent. This connects your assistant to the game without needing configuration files or API keys.
Can I customize Luna's appearance beyond just her clothes?
Yes, you have access to over 40 tools for customization. You can use detailed sliders, control points, and presets to sculpt her face, adjust skin tone, apply makeup, and change her hairstyle to suit your preferences.
What happens if I want to switch back from an external agent to the built-in AI?
You can switch back to the built-in AI at any time. The system allows you to toggle between the internal model and an external AI assistant whenever you like, giving you full control over her intelligence and personality.
How can I make the digital human perform specific dances?
You can utilize the built-in motion library to select dance or idle move presets. Additionally, the software supports learning new dances by importing MMD motion files along with their corresponding song files for a custom performance.
Is it possible to use my own expressions to control the character?
Yes, the software includes a webcam mirror feature. This allows your own webcam to track your face and body movements, driving the digital human's expressions and gestures in real time as you move.
Can the AI remember details about me from previous sessions?
Yes, if you use an external agent, it can tell the digital human your name, your preferences, and details about your life. She will keep this information in mind during your conversations to provide a more personalized experience.
How do I capture photos or videos of the character?
Use the studio camera tools to orbit freely and frame your shots using camera presets. You can adjust lighting moods and backdrops, then take photos or record video clips directly in-game to save your favorite moments.
What languages does the software support for communication?
The AI supports 10 voice languages, including English, Chinese, Japanese, Korean, German, French, Spanish, Italian, Portuguese, and Russian. The interface automatically follows your system language, and you can enable optional dual subtitles in your native language.
