Processing Error Codes
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 the Report Model feature. It automatically gives us the model URL and the Error Code.
Unsupported Format: We recognize this 3D format, but we do not support it yet.
Unknown format: We do not recognize this format.
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.
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)
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!
Textures: This error is extremely rare. A possible cause is very large textures in your model. If you see it, please contact us!
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!
Build: This error is rare. It could be caused by very large or complicated models. If you see it, please contact us!
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.
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!
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.
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.
