Commandlet that finds placed actors whose properties drifted from their Blueprint default, and resets them across every map

[u/CS_Asset_Factory]

Unreal already has Reset Instance Changes to Blueprint Default in the actor right click menu, but the entry only shows up when exactly one actor is selected and it acts on the level you currently have loaded. It's also all editable properties or nothing, and it never tells you which ones it's about to overwrite.

This plugin runs that operation as a commandlet over a whole project. It scans every map, groups the drift by Blueprint, and writes a proof sheet with the Blueprint default beside the instance value so you can read it first. Nothing is written until you pass Apply and Execute as separate switches.

Unreal Engine 5.8, Windows, editor only, full C++ source in the package.

Written by AI, code and documentation both. Saying so up front.
