Features

Smart Detection​

Content-Based Hashing​

Duplicate Asset Detector uses advanced content-based hashing to find true duplicates, not just similarly named files. This means:

  • Textures with identical pixels are detected, even with different names
  • Materials with the same parameters are identified
  • Static Meshes with identical geometry are found

Intelligent Filtering​

The plugin automatically excludes:

  • Level actors and instances
  • Engine content (unless you want to include it)
  • System files and special assets
  • Plugin content (optional)

Special Asset Handling​

Optimized detection for:

  • Materials and Material Instances
  • Textures (Texture2D, TextureCube, RenderTarget)
  • Static Meshes and Skeletal Meshes
  • Sounds (SoundWave, SoundCue)
  • Blueprints and C++ Classes
  • Data Tables and Curves
  • And many more

Safe Cleanup​

Redirect & Delete​

The safest way to remove duplicates:

  1. Automatically updates all references to point to the kept asset
  2. Deletes the duplicate asset
  3. Preserves all functionality in your project
  4. No broken references or missing assets

Delete Only​

For advanced users who are certain:

  • Quickly removes duplicates without redirection
  • Useful when you've already manually updated references
  • Use with caution

Preview Before Delete​

Always see what will be affected:

  • List of all assets to be deleted
  • All referencers that will be updated
  • Estimated disk space savings
  • Review before confirming

Flexible Scanning​

Scan Options​

  • Entire Project: Analyze all assets in your Content folder
  • Specific Folders: Right-click any folder → Find Duplicates
  • Custom Paths: Enter manual paths for specialized scans

Filtering​

  • Filter by asset type (Textures, Materials, Meshes, etc.)
  • Set minimum file size threshold
  • Exclude specific folder patterns
  • Include/exclude Engine content
  • Include/exclude Plugin content

Detailed Analysis​

Asset Information​

For each duplicate pair, see:

  • File size (disk space)
  • Number of dependencies
  • Number of referencers
  • Visual thumbnail preview
  • Asset type and package path

Wasted Space Calculation​

The plugin calculates:

  • Total duplicate size across your project
  • Potential savings per duplicate pair
  • Accumulated savings if all duplicates are removed

Export Reports​

Export your findings to:

  • CSV - For spreadsheet analysis
  • Excel - With formatting and charts
  • JSON - For custom processing
  • Full Report - Comprehensive project analysis

Important Notes​

Assets in Use Warning​

When deleting assets currently used in an open level, Unreal Engine may display a warning ("asset is already in use"). This is normal engine behavior - the redirect operation completes successfully.

For best results:

  • Close levels that reference duplicate assets before deletion
  • Alternatively, reload the project after performing redirects

Detection Accuracy​

While Duplicate Asset Detector uses advanced content-based hashing, in rare cases false positives may occur with:

  • Complex procedurally generated assets
  • Assets with similar but not identical content
  • Special engine-internal assets

If you encounter an incorrectly flagged asset, please report it via Discord or email.
