UE5 Smart Selection & Batch Rename Tool (Editor Utility Widget)

This is a tool I built to make scene management faster inside Unreal.
Unreal doesn’t natively expose a way to select actors based on the Static Mesh asset they use, so the Smart Select logic digs into the selected actor’s Static Mesh Component, parses the asset reference, and finds every actor in the level using the same mesh. If the actor has no mesh, the tool automatically falls back to class-based selection.

The live rename preview updates instantly as you type, no refresh or extra steps.
This isn’t just for renaming. The same selection feature can be used to batch-edit any shared property in the Details panel, like assigning HLOD layers, adjusting Data Layer membership, or pushing consistency fixes across a large environment.

It’s a small tool, but it fills a real gap in UE5’s editor workflow and makes high-volume scene cleanup noticeably faster.
