Pros :
1 - (Functionality) : Hey, it works! At least to play dances.
2 - (Free) : No bullshit "manually-made-single-machine-only" licenses for a plugin to a software here! Take notes, ZHFX!
Cons :
1 - (Need to manually t-pose) : You'll need from my limited experiences with this, to every time you want to play a different dance, to make the girl t-pose again and again.
2 - (Navigation hurdles) : The navigation panel for seeking vmd files could be improved (maybe like .bvh player, instead of pointing by default to the .var itself, point to a default folder in saves).
3 - (Not fluid) :As other people pointed out, the animation itself is janky.
Overall, not quite there, but I'll look behind the ugly, after all it's a alpha so it's understandable. If I find any bugs/quirks, I'll be sure to report back. Godspeed you legend.
It is really hard to get this MMD stuff right and I struggled with it to the point of just being frustrated with writing this to be honest - especially since all of this I do for fun and not a job.
Very unlikely that I will work on this more as a result. If you find someone who wants to just take it over that would be perfectly fine. The github repository is public and I would take no offense.
