Removing unnecessary geometry items from the Libray after updating Datasmith file

Is there any way to find assets not linked to a scene actor, in order to delete them from the library?

After updating a source file, and re-importing through Datasmith, assets with updated meshes — possibly split into parts, or re-created, still retain the original mesh item in the library. On large imports this leads to large amounts of duplicate and unnecessary geometry residing in the library folder.

There is no purge command as in Revit or AutoCAD, but there is a way to find unused assets:

Perfect, thank you.

Mind that there is a bug where it correctly reports static mesh assets unused, but not materials and material instances

We found that the filter wasn’t reporting more than one level deep with regards to hierarchy (ex: actor → Mesh → material instance → texture), hence it reporting partially correct information. This is now fixed internally and should make its way in 4.23 soon.

Great, thank you for addressing.

perfect solution . i use clean project plugin. works like charm. removes all unused assets and many more stuffs with two clicks. link - Clean Project in Code Plugins - UE Marketplace
