Hi 8th Wall Support Team, I’m currently building a webAR project using 8th Wall, which allows users to upload images, send them to MeshyAI to generate `.glb` models, and display those models in the scene dynamically. Everything works perfectly in the Simulator and desktop browsers — the generated `.glb` files load correctly via ``. However, when I run the same project on mobile (especially iPhone or Android Chrome), the `.glb` model fails to render, although there are no errors in the console. The file is accessible via URL, and downloads correctly if opened in a separate tab. **Question:** Does 8th Wall currently support displaying externally hosted `.glb` models (e.g. generated from MeshyAI, served via ngrok or Cloudflare Tunnel) on mobile devices? Are there any specific requirements for mobile rendering (CORS headers, file server config, MIME types, content length, etc.)? Any insights or suggestions would be much appreciated!

Do you know if the created models use 4k textures? I have had that be an issue before. It renders fine on the desktop but breaks on phone. WebGL on mobile can’t render over 2k textures. I would make sure you are keeping the file sizes down as much as possible. ---

I would also recommend taking a look at our guide here: > **[Your 3D Models on the Web | 8th Wall](https://www.8thwall.com/docs/guides/your-3d-models-on-the-web/)** > > We recommend using 3D models in GLB (glTF 2.0 binary) format for all WebAR experiences. GLB is ---

Dear Bulter, I can load the 3D model in simulator now, but can’t load the model in the Phone. The 8th Wall console do not show error either, so I am curios about that. ---

Can you land your changes and [share your project](https://www.8thwall.com/docs/guides/projects/project-sharing/#share-project-with-another-workspace) with the `support` workspace, so I can take a look? ---

Dear Bulter, I am already fixed this problem, thanks a lot! ---
