Smart Naming Cleanup is an editor code plugin for Unreal Engine designed to automatically fix, normalize, and organize asset naming conventions inside the Content Browser.

The plugin helps speed up repetitive cleanup tasks after importing assets, preparing marketplace packs, or organizing large projects by automatically detecting asset types and correcting naming issues in bulk.

Main Benefits:

  • Saves time on repetitive asset cleanup

  • Keeps projects organized

  • Helps maintain naming consistency

  • Speeds up marketplace pack preparation

  • Reduces manual batch renaming work

Included Editor Actions:

  • Scan Selected Assets

  • Cleanup Invalid Names

  • Remove Duplicate Prefixes

Preview Workflow: The plugin includes a rename preview system that allows you to inspect all changes before applying them.

Example: OLD NAME: 01_SM_SM_Wall_Wall_01 (NEW NAME: SM_Wall_01)

This helps reduce mistakes during large batch operations.

Safe Rename Workflow

Smart Naming Cleanup uses Unreal Engine asset rename workflows designed to preserve asset references and redirectors during rename operations.

Non-destructive workflow: All renames are previewed before applying changes.
