Seeing the asset was just uploaded it's not a rush. Hoyo2VRC 5.2.2 doesn't recognize Silver Wolfs SP as an HSR character but just an NPC, which doesn't allow me to convert. Blender 4.4, then downgraded to Blender 4.0. I checked tagged threads to find a similar issue, and pretty sure I'm following all the steps to import, and convert just fine as I tested this on the older SW model.
Unless I need to give time to breathe and let these receive any asset updates then disregard lol, Thanks!
edit: I have not altered anything when downloading from the repo, other than unzipping and putting these files in my own designated folder
