Here is an MVR Updater. It is a private, local first (not uploading data to server, all is processed in the web browser) tool that allows to easily update GDTF files inside an MVR zipped scene file. This is useful in a few scenarios: for older MVRs, where the GDTFs have been improved over time for MVRs coming from tools that only use placeholder GDTF files for tools that export only parts of previously added GDTFs The initial load time of the MVR Updates takes a few seconds but the upside is that any-sized MVRs/GDTFs then take no time to load, because they are all processed locally in the web browser. https://gdtf.eu/mvr/mvr_artist/
