We process many 3D formats, but sometimes things go wrong. Error codes helps us diagnose a problem and suggest a solution. The best way to report an upload error is to click the Edit Properties button on your model page.
Once there, you can click Report an issue from the bottom-left corner of the Properties page. It automatically gives us the model URL and the Error Code.
Error 10
Unsupported Format: We recognize this 3D format, but we do not support it yet.
Error 11
Unknown format: We do not recognize this format.
Error 12
Already Being Processed: We won't process the same file at the same time. You need to wait for processing to finish or fail before uploading it again. You also cannot delete a model until it has finished processing.
Error 13
Invalid Data: We could not find any file to process. It could be a format we don't recognize, or a file format version we don't support (e.g. old versions of COLLADA).
Error 20
Preprocess: Something went wrong before we tried to process the model. This could indicate a bug on our end. It can also happen temporarily during server upgrades and migrations. If you try again later and the problem persists, please contact us!
Error 21
Textures: This error is extremely rare. A possible cause is very large textures in your model. If you see it, please contact us!
Error 22
Stats: This error is extremely rare. It indicates a bug on our end that needs to be fixed. If you see it, please contact us!
Error 23
Generic: This unexpected error indicates the model failed to process, most likely due to bad data. If the error persists, contact us.
Error 30
Build: This error is rare. It could be caused by very large or complicated models. If you see it, please contact us!
Error 31
Model Options: This error occurs during material processing. Some common causes are very complicated scenes with many unique materials and textures. It can also be caused by unsupported features that we don't recognize, especially in Blender files. It's best to apply any modifiers and convert everything to meshes.
Error 40
Install: This error is extremely rare. It indicates a bug on our end that needs to be fixed. If you see it, please contact us!
Error 50
Timeout: If the model is not finished processing in 1 hour, we give up. This can happen for models with a very high vertex/face count, complicated scenes with lots of unique objects, or models with huge textures.
Error 60
WebGL: This error is extremely rare. It indicates a bug on our end that needs to be fixed. If you see it, please contact us!
Unknown Error (Error 1)
Unknown: The most common cause of an unknown error is a model that is so big or complex that processing could not exit "gracefully" with an Error 50. It could also be caused by a very large texture or many textures. Another rare edge case is a browser that produces a corrupted ZIP file; when you upload uncompressed files, we zip them on the client side before uploading. If you think your file is not too big to process, try compressing it into a ZIP, RAR, or 7z archive before uploading. This is best practice in any case to reduce file size and bandwidth usage.

Hey James, I'm working on a script to upload several models to Sketchfab automatically, but I'm having an issue where the API returns an error message saying "The model is already being processed". All models uploaded are different devices and the files have different names.
My question is, how do you guys check if a model is already being processed? Just by the name of the file? Or you check and compare hashes of the file, or model dimensions or something like that? Because some devices could be exactly the same and that would explain the error I'm getting.
Thanks in advance.
Hey, good question. We use the MD5 hash of the uploaded file to check if the same file is already being processed.
I am getting error 404 page cannot be found when attempting to upload from Revit
After the upload completes and you try to view the model? What is the URL? It looks like you have successful uploads: https://sketchfab.com/Aligned-VR/uploads
I am having the same issues as 'Aligned-VR'
The URL I am getting is this ...>>> https://sketchfab.com//uploads
The text shown on the page is as follows....
Error 404
The page cannot be found
Please check the address or go back to the homepage
It looks like the exporter might just be showing the same URL. You can find your uploads here: https://sketchfab.com/ATD-London/uploads
