Various implementations disclosed herein include devices, systems, and methods that enable two or more devices to simultaneously view or edit the same 3D model in the same or different settings/viewing modes (e.g., monoscopically, stereoscopically, in SR, etc.). In an example, one or more users are able to use different devices to interact in the same setting to view or edit the same 3D model using different views from different viewpoints. The devices can each display different views from different viewpoints of the same 3D model and, as changes are made to the 3D model, consistency of the views on the devices is maintained.
