Hi everyone,
I’m encountering a processing error while uploading my 3D asset pack to Fab. During the automated ingestion/processing step, the upload fails with the following message:
“An error occurred during the file processing”.
Here are the technical details of my package:
Primary Software: Blender (along with Cinema 4D cache files)
File Formats Included: .blend, .abc (Alembic), .fbx
Package Structure: Standard .zip archive containing the .blend file, textures directory, and cached Alembic animation data.
Things I have already verified:
Zip archive integrity is solid (no corrupt files, standard zip compression).
File and folder paths do not contain special characters, spaces, or non-ASCII characters.
Relative paths are set.
I tested it in Chrome, Firefox, and Edge browsers. I also tried it with Blender versions up to 4.x LTS. I didn’t get any results.
Has anyone run into this specific processing error recently? Does Fab’s automated parser have specific constraints regarding Alembic cache sizes, Blender Asset Browser metadata, or archive root directory hierarchies?
Any guidance or workarounds from the community or Epic staff would be greatly appreciated.
Thank you!
