Also, making MMD is like making an RPG game. Well everything needs a background. It's not necessary to use this when you're still new, but if you wanna take a challenge, try it!

And also there are a lot more such as VAC (Vocaloid Accessory) and all which is distributed widely all across the Net~

And oh yes, the tutorial can be found on youtube. However, some are not really specific, so let's say this. Press every button you can and be creative! I had a lot of fun using it! (even if i never succeeded in making a video longer that 7 seconds~)

Seriously~ why am I getting obsessed with this? It's not like anyone read this right?

And this here is my trial with a Keyboard VAC. Miku's cute right? Although I love the Kagamine twins better, Miku looked so cute as a Lat model!
