Optimizations are provided to control access to virtual content included within a three-dimensional (3D) mesh. Specifically, after the 3D mesh is accessed, then objects represented by the 3D mesh are segmented so that they are distinguishable from one another. Once segmented, then a permissions is assigned to each object or even to groups of objects. For instance, all of the objects that are associated with a particular sub-space (e.g., a bedroom or a living room) may be assigned the same permissions. By assigning permissions to objects, it is possible to control which requesting entities will have access to the objects as well as how much access each of those requesting entities is afforded.
