[UE5] Need help recovering from project rename - 600+ missing assets

Development Pipeline & Plugins

Hi everyone, I’m a solo indie developer working on a horror game in UE5 and I’ve made a serious mistake. Hoping someone experienced can help me recover.

What happened

I renamed my project files/folders directly in Windows Explorer. Now when I open the project, I get 600+ errors saying objects are unknown, and the Message Log shows 22+ entries like:

“Skipped package /Game/ナマズ/BP_Namazu has a valid, mounted, mount point but does not exist either on disk or in iostore. The uncooked file would be expected on disk at ‘C:/Users/…/Desktop/Content/ナマズ/BP_Namazu.uasset’. Perhaps it has been deleted or was not synced?”

Multiple assets affected: Blueprints, Megascans foliage, materials, static meshes, etc.

Current state

  • Engine: Unreal Engine 5 (Blueprint-based, no C++ as far as I know)
  • The .uproject file and Content/Config/Saved/Intermediate folders are currently scattered on my Desktop (not in a clean project folder structure)
  • There are multiple .uproject files and multiple potential Content folder candidates on the Desktop
  • I have NOT saved the project since the issue occurred (so the .uasset files on disk should still be intact)
  • No version control - lesson learned
  • Autosaves exist in Saved/Autosaves/
  • I’ve already made a full backup copy of my Desktop to another drive

What I need help with

  1. How to identify which .uproject file is the “correct” one
  2. How to properly reorganize the scattered Content/Config/Saved folders back into a working project structure
  3. Steps for Fix Up Redirectors and cleanup after reorganization
  4. If anyone is available for a screen share session, that would be a huge help

I can share screenshots of the Desktop state, the Message Log errors, and any folder contents needed.

Thank you in advance to anyone willing to help.

See below. The first option will remove redirect references. The second, likely the one you need, will update references to what they should be. Use them in order. Though, I can’t guarantee positive results depending on how many things you’ve renamed.

Thank you so much for the quick response! Before I try these options,
I want to make sure I understand my situation correctly, because I
think it might be more severe than typical rename issues.

In my case:

  • I didn’t just rename assets in the Content Browser
  • I renamed the PROJECT itself and moved files around in Windows
    Explorer
  • As a result, the project’s Content/Config/Saved folders are now
    SCATTERED across my Desktop, not in a clean project folder
  • The errors say files don’t exist at expected paths like
    ‘C:/Users/…/Desktop/Content/ナマズ/BP_Namazu.uasset’
  • I’m worried “Resave All” might lock in the current broken state
    (missing references) permanently

Questions:

  1. Would “Update Redirector References” still help if the actual
    .uasset files are physically misplaced (not just renamed)?
  2. Is “Resave All” safe to use when many references are currently
    broken? I’m afraid it will permanently save the “missing” state.
  3. Should I first reorganize the scattered folders back to proper
    project structure before trying these options?

I attached screenshots of my Desktop state and the Message Log errors.
Any guidance would be hugely appreciated. Thanks again!
