Hi everyone,
I’m trying to publish a Unity format package on FAB, but the upload keeps failing with a generic error message.
Issue
When uploading my .unitypackage file in the Unity Game Engine Formats section, FAB shows:
“These elements have not been successfully uploaded.”
File:
AtmosphericFarmhouse_Full.unitypackage“An error occurred”
The upload never completes even after retrying.
What I’ve Tried
-
Retrying upload multiple times
-
Refreshing the page
-
Re-exporting the Unity package
-
Using a different browser
-
Checking internet connection
Current Setup
-
Package type:
.unitypackage -
Asset category: Environment / House
-
Unity format added under Included Formats
-
HDRP + URP selected
Questions
-
Is there a file size limit for Unity packages on FAB?
-
Are there specific Unity export settings required?
-
Does FAB reject packages containing certain folder structures or unsupported files?
-
Has anyone experienced this exact upload error recently?

Any help would be appreciated. Thanks!
