A Plattar-formatted 3D model is a .zip file containing a .gltf ‘mesh’/model file, and any images needed. You can create/convert your models to this format by using the Creating a glTF guide.

3D models can have animations that will repeat in a loop when they are viewed in a scene. You can use many 3D models at once, but be careful that the scene downloads in a reasonable amount of time, and performs ok on your user’s devices.
