Asset Upload Failed: "An error occurred during the file processing" for Blender / Alembic files

[Yaratici_Etkiler]

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!

Hello friends,

I have also tested the project using Blender 4.5.

I imported the project files into Blender 4.5 and exported them as a .blend file. However, when I attempt to upload this file to the Blender section of my product listing, I continue to receive the error message: “An error occurred during the file processing.”

I would like to include Blender files in my listing, but this issue is preventing me from proceeding. Could you please assist me in resolving this?

Thank you…
