First, find an object you would like to use. Go to poly.google.com and log in with your Google account. Search Poly’s repository of objects. Once you find your desired object, simply “like” it by clicking the heart. Note that you will only be able to use others' objects if they are remixable (marked "Public/Remixable CC-BY"). Otherwise, it will not import into your TiltBrush workspace.
If you have created your own file you’d like to upload, upload the .obj file to Poly and publish it. You will not be able to use the item in Tilt Brush unless it is published, though you may change the permissions and access settings.
Follow these steps to import an object of your own or one from someone else.
Log out of your Google account on the headset when you are finished.
