Asset Deduplication Tool

It’s common for developers to accidentally duplicate assets—like copying a texture to test something and forgetting to delete it. The Asset Deduplicator finds these files.

How it Works

The tool calculates a hash for every asset in your project (specifically targeting Textures, Audio, and Meshes). If two files have the same content (even with different names), they are flagged.

Using the Tool

1. Open Tools > Scene Size Analyzer > Asset Deduplicator.
2. Click “Find Duplicates”.
3. Review the groups of duplicate assets.
4. Action: Select the assets you want to keep and delete the duplicates. Update references in your scenes (pro-tip: use “Select Dependencies” in Unity to find usages).

Performance Note

Hashing thousands of large textures can take a moment. The tool runs on a background thread where possible to keep the editor responsive, but large projects may experience a brief pause.
