📘 Unity 6.2 Beta AI Features – FAQs & How to Use Guide

🔍 FREQUENTLY ASKED QUESTIONS (FAQs)

Q1: What is Unity AI in 6.2 Beta?

A: Unity AI is a unified set of artificial intelligence tools that includes formerly separate tools like Muse and Sentis. It enhances workflows through generative AI, automated asset creation, behavioral programming, and real-time AI integration.

Q2: What is the difference between Muse and Sentis?

• Muse focuses on editor-time tools (asset creation, code assistance, behavior design).
• Sentis enables runtime integration of neural networks, so games can use AI models during actual gameplay.

Q3: Is Unity 6.2 Beta free to use?

A: Yes, the Beta is free to try for Unity developers with eligible plans (Personal, Pro, Enterprise). Some AI features like Muse may require additional licensing or subscription in future releases.

Q4: Can Muse generate code?

A: Yes. Muse Chat can write, explain, and modify C# scripts using project-aware, context-sensitive AI assistance directly inside the Unity Editor.

Q5: Are AI-generated textures and sprites copyright-safe?

A: Yes. Unity claims Muse-generated assets are commercially usable, and ownership belongs to the developer who generated them, per Unity’s terms.

Q6: Can I import my own ML model into Unity?

A: Yes. With Sentis, you can import ONNX-format machine learning models and run them inside your Unity project on various platforms including desktop and mobile.

Q7: Does this work with 2D and 3D games?

A: Absolutely. Muse supports both 2D and 3D workflows, and tools like Muse Sprite and Muse Texture are tailored for both environments.

Q8: Is coding still required?

A: Some coding is still necessary for complex logic, but Muse and Muse Behavior can significantly reduce the amount of boilerplate code you have to write.
