Parts of model become see-through in AR scene

[Jasonp8000]

Hi everyone,

I've noticed when viewing a model in the AR scene parts of the model become see-through. Has anyone else had this issue ?

Is this in Scene Viewer mode? This is due to background occlusion and it has erroneously found your scene's background to be closer than it really is (it's a tricky problem). I believe you can disable this feature in the top-right of the screen. You won't see this in WebXR mode as we don't support background occlusion yet.

yeah - it's occlusion - you can switch it off, there's a button at the top

I'm new to using model viewer, which button an you referring to? Can occlusion automatically be turned off?

[SGECZ]

and yes, it can

Is this different for iso devices? I'm using an iPhone 12 pro.

Yes, Scene Viewer is Android, while Quick Look is iOS. This is why it is always key to note your device, OS, and browser when asking a question. I don't think they have this option in Quick Look. Please file a bug on Apple.

Just to follow up on this - I noticed a similar effect seems to happen when faces are detected (at least on iOS / Quick Look). The model becomes see through to show the face. Is this the same setting, and only available on Android? I couldn't find an attribute in the model-viewer documentation to ignore facetracking.

Definitely not a MV setting, and if it's on Quick Look, then it's not Android either. You'll have to check Apple's docs.
