Techniques configured to enable multiple users to dynamically and concurrently edit a scene that is viewable in a three-dimensional immersive environment are described herein. The techniques use region locking so that content being edited by one user viewing and editing the scene in a three-dimensional immersive environment cannot be edited by another user concurrently viewing and editing the same scene in the three-dimensional immersive environment. Accordingly, a scene can be divided into multiple regions that can be locked to provide an element of protection against user interference that can result when two users are editing, or attempting to edit, the same content.
