AssetsTooling is an Unreal Engine editor plugin that scans your project's assets and reports quality, organization, and integrity problems — while keeping the editor fully usable during the scan.

Most Unreal Engine tools that inspect content either freeze the editor while they run or require you to check assets one at a time. AssetsTooling was built to address both problems: it runs all checks on a background thread and inspects the entire project in a single pass. The editor stays responsive, and results are presented together in a dedicated panel when the scan finishes.

The plugin only runs inside the editor. It has no runtime component and adds nothing to a packaged game.

AssetsTooling performs eight categories of checks across all project assets:

AssetsTooling v1.0: Broken References - Unused Assets - Naming Conventions - Missing Source Files - Texture Audit - Mesh LOD - Stale Redirectors - Duplicate Assets.

AssetsTooling Extended v1.1: Commandlet Integration - On-Save Validation - Texture Compression and Group Validation - Blueprint Node-Graph Validation - Structured Report Output - Settings Snapshot for Thread Safety ( Most of these tools are called on asset import or saving)

The plugin scans only assets inside your project.
