Abstract: Example embodiments are disclosed relating to virtual content. Example embodiments may involve providing video data for output to a user device, the video data representing a virtual scene comprising one or more virtual objects at respective locations in the virtual scene with which a user of the user device may interact during an interactive session. The interactive session may be paused and a resumption input may be received at a second time, subsequent to the first time, for unpausing the interactive session. Responsive to receiving the resumption input, it may be detected that interaction with a particular virtual object, with which the user has interacted prior to the interactive session being paused, is restricted due to physical properties of a real-world space in which the user is located at the second time. The virtual scene may be modified to permit interaction with the particular virtual object without the detected restriction.
