Unreal Asset Cleaner is an editor utility plugin designed to help developers quickly scan, review, and clean assets inside Unreal Engine projects.

It checks selected assets or complete Content Browser folders for common issues that can affect project quality, organization, performance, and marketplace readiness.

The plugin analyzes Static Meshes and Textures and presents problems in a clear severity system using Errors, Warnings, and Reviews, so you can immediately see which assets require attention and which ones only need a manual check.

Key features include:

• Static Mesh triangle count checks

• LOD validation

• Nanite checks

• UV channel validation

• Collision review

• Material slot checks

• Missing material detection

• Texture resolution checks

• sRGB validation

• Normal map compression checks

• Detection for Base Color, Normal, Roughness, Metallic, AO, Mask, and packed textures

• Safe automatic texture fixes

• Redirector detection and cleanup

• Optional naming convention checks

• Customizable scan thresholds

• Search and severity filters

• Direct asset selection in the Content Browser

• Recursive folder scanning

• Folder context-menu integration

• TXT and CSV report export

The tool is designed to make asset validation faster and more consistent, especially when working with large asset packs, marketplace content, environment packs, or production projects with many assets.
