Frequently Asked Questions

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

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.

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.
