Man, this is really cool! The dance transitions are smooth but a little more variation would be nice. I liked the gaze feature of slut+ but the face she made was too much. Maybe try Expression randomizer for more subtlety to the expressions. The fact that you can load your own music in game is pretty special. I wanted that feature a while back for a mini-game scene of mine but couldn't figure out how to do it without scripting (which I really didn't want to do). And, you motivated me to figure out VR passthrough finally. I managed to kind of get it to work by changing background to black (in SteamVR w/ Valve Index), but that meant all black items in the scene were invisible. Still a cool effect to see the girl dancing in my room and maybe I'll eventually figure out how to use the green screen.
Oh, and one last thing, for some reason the first time I loaded, none of the menus appeared. But a quick reload (not even restart VAM) fixed it. Strange. There was a plugin I had to enable for the first time, so it was probably that. But I'm pretty sure it wasn't VAM Story which would be an obvious suspect.
Keep up the good work.
