Error on running sandbox scene

🌵 Needle Engine
1

I create the sandbox scene and try to run it on localhost. Most of the function works fine but when I use my iPhone and run the AR mode, it fails to load the texture, and it seems like all the components combine into one object, so I can’t drag the specific object , anyone know why?

Hi William!

It seems like you are encountering issues with loading textures and object interactions in AR mode on your iPhone. Here are some common reasons and solutions:

  1. Texture Loading Issue:

    • Ensure that textures are properly referenced and accessible. Textures may not load if they are too large or not in a compatible format (e.g., JPG/PNG).
    • You can check if your textures are set to use compatible settings in Unity or your export tool.

  2. Object Combination:

    • When objects appear combined, check if they are all part of a single parent GameObject or incorrectly grouped in your scene hierarchy.
    • Ensure that the components you expect to be separate are not being merged or nested unintentionally during the export or setup phase.

  3. AR Functionality:

    • Make sure you have included the required WebAR components in your scene. Specifically, the WebXR component and optionally AR Session Root for proper placement and functionality in AR (see releases) (see releases).

  4. Configuration for iOS:

    • Verify that your AR configuration is correctly set for iOS. Different device settings in AR can impact how meshes and textures are rendered.
    • You may want to check logs for any errors that might indicate issues in asset loading or configuration settings when accessed from your iPhone.

  5. Browser Compatibility:

    • Make sure you are using a compatible browser on your iPhone that fully supports WebXR. Safari is typically the preferred option, but you might want to test it on other browsers too.

If the above suggestions don’t resolve your issue, consider posting detailed error messages from your browser’s developer console, as that could give further insights into the textures not loading.

Feel free to ask if you need more specific guidance!

Hello William

The sandbox scene models all use vertex colors. I’m not sure if those are 100% supported in Quicklook/USDZ export at the moment. Models with normal materials+textures (or colors) work fine tho. CC @Felix_Herbst for more info
