Frequently Asked Questions

"No importable file found" - What does this mean?

This error occurs when none of your uploaded files are in a supported format. Our 3D viewer automatically detects importable files by their file extension. Please check if your file format is listed in our supported formats, and ensure you're using the correct file extension.

"Failed to load file for import" - What does this mean?

This means our system detected a supported file format, but couldn't load the file. This typically happens when trying to load a model from an external URL.

To troubleshoot:

• First, test if your URL works in a browser window
• If it works in browser but not in our viewer, it's likely a CORS (Cross-Origin Resource Sharing) policy issue
• CORS issues occur when the server hosting your model doesn't allow requests from different origins
• If the URL doesn't work in browser, the URL itself is incorrect and needs to be fixed

"Failed to import model" - What does this mean?

This indicates that a supported file was found and the import process started, but failed during processing. If the error message doesn't provide enough information, please report the issue on our GitHub repository with details about your file format and size.

Why does my model work locally but not from a URL?

This is almost always caused by a CORS (Cross-Origin Resource Sharing) policy violation. The server hosting your model doesn't allow requests from different origins. To resolve this, the server administrator needs to configure CORS settings to allow requests from our domain.

Why is my model completely gray?

Some file formats (like STL files) don't include material information, so models appear with a default gray color. You can easily change this color using the settings panel on the right side of the viewer.

Additionally, some formats (like OBJ files) often work with separate material files (MTL files). Check the files panel for any missing material files, and if you have them, import them together with your main model file.

Why does sharing fail?

Our 3D viewer doesn't store models on our servers - everything happens in your browser for privacy and security. Sharing is only possible if your files come from an external server that's publicly accessible.

For example, you can share a model that's loaded using the "Open URL" button, but models uploaded via drag-and-drop or the "Open" button are not publicly available, so sharing isn't possible in those cases.
