hi @EsmeeSays ,
Have you tried using the asset fix up
Validation and Fix-Up Tool in Unreal Editor for Fortnite | Unreal Editor for Fortnite Documentation | Epic Developer Community
and the Manual fixup
These are the recommended tools by Epic Support after an update, while you wait for Epic to check the report.
Has this just happened as a result of 35.10? If so, can you add the version number to your title, please? This makes it easier to search for the reports for us indie developers
The new Fortnite Ecosystem v35.10 with Known Issues - General / Announcements - Epic Developer Community Forums
has information
Here is more detailed instruction found on Google
Here’s a more detailed breakdown:
- Identify the Offending Asset:
- UEFN Validation Errors:
If your project is failing validation before uploading, the editor will identify the disallowed assets in the output log. Look for lines indicating “Found disallowed object type” or similar messages.
- Output Log:
The output log will provide a file path for the disallowed asset. You can use this to locate the asset in the Unreal Engine editor.
- Scene Outliner:
If you’re unsure where to find the asset, try using the Scene Outliner to locate the offending actor. You may need to expand different levels or sub-levels to find it.
- Fix the Disallowed Asset:
- Automatic Fix-Up:
If the validation error provides a fix-up option, use it to automatically revert properties.
- Replace or Remove:
If automatic fix-up doesn’t work, you’ll need to manually replace the disallowed asset with an allowed one, or remove it and add a new one from the content browser.
- Device Settings:
If the disallowed asset is a device, you might be able to revert device settings to fix the issue.
- Wait for Updates:
Some validation errors may be fixed in future Unreal Engine updates. If you cannot fix it yourself, you may need to wait for the next update.
- Hidden Properties:
If the issue is related to hidden properties, you may need to revert them to their default values or remove them entirely.
- Use the Validation and Fix-Up Tool:
- Asset Fix-Up:
Select the disallowed asset(s) in the Content Browser, and use “Asset Actions > Fix Validation Issues” to run automatic fix-up.
- Actor Fix-Up:
Select the disallowed actor(s) in the Scene Outliner, and use “Fix Validation Issues” to run automatic fix-up.
- Manual Fix-Up:
If you need to fix a specific property, look for “Reset Property to Default” in the validation error message.
- Example Scenarios:
- Disallowed Object Type:
If you encounter “Found disallowed object type” error, try removing the Player Spawn from your Game and adding a new one from the content browser.
- Disallowed Engine Assets:
If the error refers to engine content like “T_Default_BaseColor,” you’ll need to replace the reference to that texture in your material instances or material graph.
By following these steps, you can effectively address disallowed assets in your Fortnite Creative projects.
