Unity Asset Manager — March 6, 2026

New tracking file system: Tracking data now resides in `/uam/` and mirrors the `Assets/` folder structure. Each Unity asset file has a human-readable `.json` tracking file. This structure makes it easier to locate and review how imported cloud assets map to files on disk.

New tracking file system: When you move assets inside `Assets/` , their tracking files move with them and cloud links are preserved automatically. Commit the `uam/` folder to version control so your team shares the same tracking state and import history. For more information, refer to the Tracking files documentation.

Automatic migration from the legacy tracking format: Projects that upgrade from versions earlier than 1.10.0 are automatically migrated from the old `ProjectSettings/.../ImportedAssetInfo/` location to the new `uam/` structure. You can also run the migration manually from the Asset Manager window if older files appear after a version control update.

Control automatic tag generation: A new toggle lets you disable automatic tag generation during uploads, including tags based on file types. This option gives you more control over asset metadata and helps maintain consistent tagging in structured pipelines.

Responsive upload cancellation: You can now cancel uploads immediately. This change lets you stop uploads quickly if you need to cancel a batch or correct a mistake.

Stable GUIDs across asset versions: Moving files between asset versions no longer regenerates Unity GUIDs. This change preserves the GUIDs and keeps scene and prefab references intact across asset updates.

Stable GUIDs across asset versions: For more information on other fixes and improvements in this release, refer to the full changelog.

Enhanced onboarding experience: The new Asset Manager Home page provides quick access to video resources and onboarding guidance. Use the Getting started section to set up your Asset Manager workflow and explore available features.

Enhanced onboarding experience: Use the Latest assets section to view assets you recently used and filter them by uploader. The Recent threads section shows active discussions related to your assets.

Enhanced onboarding experience: The page also displays all projects in your organization in an updated layout that improves browsing and discovery. Select Show all to open the assets in the library view.

Environment, Lighting, and Background tools: You can now preview 3D assets in different environments with directional lighting and HDRI rotation. You can also change the background color, enable or disable the HDRI background, and blur the background. These controls help you evaluate materials more effectively by viewing them under different lighting conditions, environments, and backgrounds.
