I spent quite a large amount of time trying to figure all this out. As an outside observer, I found it hard to figure out that this was a thing...and not just some random folder. I figured that "MediaVPs" was most likely higher resolution videos, if it wasn't just the videos outright, as that's what "Media" tends to imply. It never occurred to me that it was a mod I should launch the game from.
It looks like a lot of work has been put into this, and I'm a bit sad I missed it during my playthrough. I think that believing my occurrence is a one time problem would also be a mistake...the only reason I caught it is because of my natural curiousity, and many people would have just never realized anything was missing to begin with.
Out of curiousity, would there be any way to make this all as a check box on the actual launcher to turn on these models/sound files etc? I know, I know, different teams...but it seems like the work you guys are doing could be applied to all the mods. I don't know enough about the games infrastructure, but it's a shame that your models can't be something to port into everything, and require their own launch.
At any rate, keep up the good work. I like what I've seen so far.
