Licensing & Content Origins
Ambient City is a curated and modernized collection of characters, animations, and tooling designed for ambient population and city-life scenarios in Unity.
Some of the underlying character and animation assets originate from content originally released by Microsoft under the MIT License. These assets were historically distributed as part of Rocketbox-style character libraries and have been widely used in real-time applications, visualization, and games.
Why this content is included
The original assets provide a strong foundation for believable background characters, but were not authored with modern Unity workflows in mind. Ambient City builds on this foundation by:
reorganizing content into focused, modular packages
standardizing folder layout and naming
providing demo scenes and visualization tools
adding editor tooling and automation
applying import-time fixes for legacy export issues
These changes significantly improve usability and integration while preserving the original creative intent of the assets.
Licensing model
Ambient City as a package is distributed under the Unity Asset Store EULA.
However, in accordance with open-source requirements:
Components originally released under the MIT License retain their original license
The full MIT license text and attribution are included in this package
No additional action is required for typical game or application use
You are free to use the content in commercial or non-commercial projects, including shipped games and applications.
Why you can purchase this package
The MIT License explicitly permits redistribution and commercial use.
What you are purchasing with Ambient City is not a change in license of the original assets, but the value added through curation, tooling, documentation, support, and ongoing maintenance.
This approach is common across the Unity Asset Store and the broader software ecosystem.
Redistribution note
If you redistribute the Ambient City package or its contents outside of a built application (for example, as part of another asset package), you must retain the included third-party license notices, as required by the MIT License.
For normal project use and game distribution, no additional steps are required.
In summary
Ambient City is sold under the Unity Asset Store EULA
Some components originate from MIT-licensed source content
Attribution is included and handled for you
Commercial use is fully permitted
The package focuses on convenience, organization, and production-ready workflows
