I just tried myself, the ‘panda.egg.pz’ file if thats what you mean, convert to x format. I don’t know if the converter has any problems, but I can tell you that when I was still choosing between engines I exported my models to the x format alot and I can remember that the x exporter was really buggy sometimes, don’t remember the same for the importer.
