How to Import External USDZ 3D Objects into Reality Composer

With the free Reality Composer app for iPad and iPhone you can create your very own Augmented Reality (AR) experiences with relative ease. In this QuickTips tutorial I’ll teach you how to import external 3D models using the USDZ file format to further improve your own AR creations.

By following this tutorial you’ll also learn how to download and import USDZ files from different online sources, including NASA ( You can bring these models into your own Reality Composer projects and use them just like you would any of the default built-in objects. This opens up a whole new range of opportunities and creative possibilities for your projects.

Here’s a quick guide on how you can import USDZ files, which are Apple’s own 3D format, straight into Reality Composer. You can get USDZ files from lots of different places, or you can make them yourself using apps like Clone. Check out the 3D Warehouse and the NASA website linked below; it has loads of great models. In fact, I’m going to use the NASA website now. I’m going to scroll down until I find a model I like the look of, and I’m going to download that into the Files app on my iPad.

Now, let’s jump straight into Reality Composer, where I’ve got a new horizontal workspace, and I’ve deleted all the objects on there. So, let’s press the plus button to add a new object. This time, we’re going to add a new one from a file. So, we’ll tap on the plus button, and then we can navigate using the Files app to find our download. When I import it, you should see it drop straight onto the page, just like any other object from the Reality Composer library. And of course, you can manipulate this by moving it through the x, y, and z axes. You can change the scale, you can rotate it, and position it wherever you like.

Another way to get your new models into Reality Composer is to swipe up from the bottom of your iPad to show the dock, and then drag the Files app over to the side of your screen. Navigate to the folder where all your downloads are saved, and you can literally drag and drop straight from Files onto Reality Composer and drop it where you want on the page. Really simple and really quick. And again, you’ll get that fully detailed model ready to go.

When you press the AR button in the top corner, you’ll get to view your new models up close. And the USDZ file format allows for loads of detail and precision. So, if we get really close to the Mars Rover, you can see all of the detail there on that model from NASA. Again, all these NASA models are completely free, and there are loads more online as well, which can interact with your existing models and objects in Reality Composer. The possibilities are truly endless.
