In a 3D Models True Space experience, you can provide an end-user multiple models for viewing in augmented reality - accessed via a carousel menu on their mobile app.
In AR Designer, the 3D Models component features a separate card for each model. Select the button at the top right to add more model cards to your experience carousel. You can make up to 20 models available.
Within each model card, you may upload another .fbx model file and give it its own name, thumbnail, description, and button link.
To delete a card, select the trash can icon.
