Troubleshooting & FAQ

The content wobbles or drifts

This is almost always the target image. Glossy, plain, blurry, small or repetitive images are hard to track. Use a detailed, high-contrast, matte image, printed large and lit evenly, and hold the phone reasonably still. See Choosing a target image.

Nothing appears in the viewer

• Make sure you tapped Start AR and allowed camera access.
• Point the camera at the correct target image, with the whole image visible and well lit.
• Check the project is still published (an unpublished link won't open).
• Make sure the project isn't locked - a locked project's link goes dark (see below).
• Try a modern browser - Chrome on Android, Safari on iPhone.

My project is greyed out, or its share link stopped working

You're over your project limit, so the oldest projects beyond it are locked: they're greyed out on the dashboard and their public link is offline. This usually happens after a plan downgrade. To bring one back, click Unlock on that card to buy a project slot for it, or upgrade your plan so your limit covers it. Students should ask their teacher. See Dashboard & projects.

Taps don't do anything

• Confirm you added an On Tap node for that object and wired it to an action.
• If a node shows a warning badge, the object or scene it referenced was deleted - re-select it in the node.
• Test in Preview first - if it works there, it will work in AR.

My object won't fade / opacity looks wrong

Add an Opacity track to an animation clip and set two keyframes with different values (for example 0 then 1). Scrub the red playhead to preview the fade in the editor. Make sure the clip is set to autoplay, or triggered by a Play Animation action, so it actually runs.

Publishing says the target couldn't be built

Your target image is likely too plain or too large. Pick a more detailed image and try Publish again. Your project is saved regardless, so nothing is lost.

A 3D model looks wrong or is huge/tiny

• Very large models are auto-scaled on import, but you can still adjust Scale in the Inspector.
• For OBJ models, import the .obj, .mtl and textures together so materials come through.
• Assign materials to tweak how surfaces look.

Can people use this without installing an app?

Yes. The viewer runs in a normal phone web browser - your audience just opens the link or scans the QR code.
