Deleted Objects Reappering

Hello,

This has been a super annoying reoccurring issue that I cannot figure out to fix. Though am new to UE5 as a whole (about a year and a half of experience) so I may be missing something.

I have objects in my content browser that were once in my editor, but I took it out and kept it in my browser incase I want to reuse it. However, if I do not open my file for say a few days, when I reopen it every single object that was once in my editor is back into it, leaving me having to parse through incorrect and correct meshes, materials, etc.

So for example, I have this one huge building that I replaced with a smaller version of it that had some changes. The huge building is still in my content browser but no longer in the editor. Then I do not touch the file for a few days, I come back, and boom both the huge building and its smaller replacement are in the editor. This does not happen, say if I open the file a few hours later or the next day. This goes on with over 10,000 assets that need to be cleaned up every time.

If anyone has a solution to this, it would be greatly appreciated! If the only option is to delete it from the content browser, is there a way to delete or select unused objects in the content browser?

Thank you so much!

There is a filter for that.
But watch out not all assets are placed in levels.
Game Modes & Player Controllers will show up with this filter if it is by itself.

You can mix it with other filters to get specific objects like static meshes or blueprints.

You could try getting rid of the folders:

  • Derived Data Cache
  • Intermediate

They will be rebuild on startup. Maybe you have corrupted cache.
