World tracking - 3D model not anchored


I have created a world tracking experience using an animated 3D model. The model places fine to begin with but there is some movement within the environment when the device is moved around after hitting “tap to place”. It seems it isn’t fully anchored to the environment. Does anyone have any suggestions why this might be/ what I can do to improve this please?


Hi @charlotte.harrison,

It’s hard to tell without seeing the project, do you have a video recording of this in action or the published project link that we could test?

I believe the instability might be down to the ground plane you are trying to place your content on. World tracking works best in well-lit environments with distinct features and textures. A plain unlit surface will struggle to build a map and therefore have unstable tracking.
