Hi! I checked out your project and didn’t encounter the issue on my personal device, but I believe I understand what you’re referring to:
Looking at the model in your project, here are some key points to consider:
- The model has an extremely high triangle count. For a non-animated graphic like this, I highly recommend simplifying the geometry. Specifically, you can map your graphic as a texture onto a quad. This change would reduce the polygon count from 2.2 million to just two polygons.
- The model is a massive 77.97 MB. While this might be manageable in Unity, it’s excessive for web-based applications. Ideally, you should aim for model sizes around 4-5 MB for web usage. I suggest running your models through the optimization tool at gltf.report and exporting them with Draco compression for significantly smaller file sizes.
- The model isn’t positioned at the origin. Image targets assume the content is centered at the origin (0, 0, 0). Any deviation will cause the model to appear offset. Ensure that your model is properly aligned to avoid this issue. Same thing goes for scale. Ideally you want the scale of your entity to be 1, 1, 1. I would adjust the scale in your modeling program.

Once you take a pass through these items I’d be happy to take another look if you’re still encountering issues,.
