I've looked at some of my previously published models that has been "verified" - most of them didn't pass missing required textures (because for me makes no sense include metallic maps for objects that have zero metalicity in them) and allowed characters (no idea about that, because all my assets follow the same naming convention and yet some of them pass the requirement and some don't). It would be nice if the system would give clear explanation where exactly the issue is, otherwise it's a big waste of everyone's time to try and guess what's on the mind of that algorithm.
