A method performed by an XR rending device (124) having an NCOD (199) for generating, for a first user, XR content for an XR environment with which the first user is interacting. The method includes obtaining first user preference information for the first user, the first user preference information comprising sensory permission information indicating, expressly or implicitly, one or more sensory stimulations to which the first user agrees to be exposed. The method also includes obtaining XR scene configuration information for use in generating XR content for the first user. The method also includes generating XR content for the first user based on the sensory permission information and the XR scene configuration information such that the generated XR content does not comprise XR content for producing any sensory stimulation to which the first user has not agreed to be exposed. The method further includes providing the generated XR content to an XR user device worn by the first user, wherein the XR user device comprises one or more sensory actuators for producing one or more sensory stimulations.
