Most current software support the Industry Foundation Classes (IFC) transfer of Building Information Models (BIMs) to applications enabling Virtual Reality (VR) navigation (BuildingSMART, 2020; Kiviniemi, Tarandi, Karlshøj, Bell, and Karud, 2008; Poljanšek, 2017). However, a review of current industry practice and scientific literature shows a rupture between the information concerning the materiality of objects stored in the IFC model data and the texture mapping image-source determining the objects' appearance in VR environments. This document presents an application based on the IfcOpenShell library (IfcOpenShell, 2020), which provides a mapping table allowing to align the retrieved relevant IFC model data to any chosen set of image or pattern files. It produces a DAE file and a linked repertoire defining texture mapping onto model objects visualised in VR. The application also allows the automatic updating after modification of the original model.
