Disclosed herein is a system that allows for the real-time build out of a virtual environment. The system and methods receive, via a web browser, a user selection of a three-dimensional (3D) model in a virtual environment. The user selection is made during an active user session of the user. Based on receiving the user selection, an editor is launched from within the web browser. The editor is used to modify properties of the 3D model in real-time during the active user session. One or more user inputs are received indicating the properties of the 3D model to be modified. Based on the one or more user inputs, the properties of the 3D model are modified in real-time. The 3D model is rendered to reflect the properties within the virtual environment during the active user session.

Aspects of the present disclosure are directed to group travel between artificial reality (XR) destinations. Currently, users in an artificial reality (XR) experience cannot travel with a group to a specific destination or between destinations (e.g., to and from virtual worlds, levels, applications, etc.). Thus, some implementations assign users within a group in a multiplayer XR experience (e.g., a virtual lobby) a same session identifier. When the users select a destination, some implementations can provide a computing system hosting the destination with the session identifier associated with the users, such that the hosting computing system can ensure that the users travel to the same instance of the destination together. If a user does not already have the destination installed, some implementations can allow the user to acquire access rights to the destination, then travel to the same instance of the destination as the other users.
