The study focuses on Palazzo Carignano in Turin as a case study and connects archival studies and Scan-to-BIM-to-VR workflows into semantic HBIM modelling while producing artifacts and character modelling while generation actors by following the narrative design. Using Unity is used as integration program and Meta Quest 3 as XR unit, project’s output is finalized through an optimized HBIM system for Meta Quest ready standalone serious game.
