How to Convert VRoid Studio to MMD With One Click

If you are a frequent reader of my articles, you probably know about my whole  “Little Old Lady Who Swallowed the Fly” problems! I really just want to write one article, but then there’s something I need to write about beforehand so that my article will be better. Sometimes I never get past swallowing the goat to catch the dog, but I always hope that eventually I’ll swallow a horse who will break free and allow all of the other animals to live their best lives.

However, this article isn’t about me – it’s about how to convert VRoid Studio into MMD, or more correctly, how to convert VRM models to PMX.

What is VRoid Studio?

VRoid studio is dope and you can Download it Here. In the most simple terms, it’s like a doll maker for programs like VRChat. You can play with sliders and edit textures to create your own models. For me, a big thing is that the program is portable, meaning no installation. There are a ton of tutorials for all aspects of VRoid Studio, so I’ll just skip to the end.

Once you are done making your model or editing a preset, you need to go to the “Camera / Exporter” tab and choose “Export” in the side bar. Once you are there, just click the “Export” button right above the “Export Hair to OBJ (Quad Mesh)”

If the model is one hundred percent for your personal use, you can ignore the window that pops up and just press “Okay”. All of that stuff really only applies if you are uploading to VRhub, a service hosted by Pixiv that allows you to share and download VRM models.

How to Convert VRM Models to PMX Models

It’s impossible for an average American to download the software you need from the creator of the software as it is hosted on Baidu. It would be possible if you bought a Chinese phone number for it, but I don’t think many people would even know where to start with that.

I was lucky enough for a nice lady to show me a copy of the software with a Japanese ReadMe file on BowlRoll. Bowlroll is a popular Japanese file sharing site. The nice lady sent the link over DM as opposed to as a reply, so I have a feeling I’m not supposed to share the link. So instead, I’ll send you on a scavenger hunt!

The first part is the easiest. You just need to find the password! Go to the VRM to PMX Converter’s home page and look under where it says “Download”. The password is in that section. (This is probably too much of a hint, but the password isn’t in Chinese.)

Now that you know what the password is, open up BowlRoll. Search for “VRM2PMXConverter” (without quotes) and you’ll find it!

This program is also portable and doesn’t require an install. I was a little dishonest with the title, however. It instead takes three clicks. After loading in the VRM file, you should see an avatar of your VRM file and the option to convert to PMX will be available.

The converter can take a bit of time to convert, but that’s barely a con when it does almost everything you need to directly put your VRoid Studio model into MMD. The file with the PMX model is placed in the same directory as the VRM model in a folder called “PMX Export”. Because of that, it may be a bad idea to convert all of your models in the same folder.

Sorry for the choppiness!

As you can see, all of the physics are preserved! For a lot of people, the article ends here. You did it! For other people, there are a few changes that need to be made.

Make Bone Groups

In a previous article, a reader asked why there were no diamonds in the bone panel in MMD.

In the conversion process, no bone groups are created for the new model. For people who only use premade motions, this is no issue. If you make your own motions, however, taking a look at this article may be helpful.

One of the problems that seems the biggest but has a really simple solution is the body poking out from behind the clothes.

I wrote about this previously with my Camila model. All it takes is deleting the parts of the body that will always be hidden behind the clothes to fix it. The best way to do this so that there isn’t any crazy jagged lines is to use the “Knife” tool in the “Adv” popup in PMX Editor, cut out a section. Then, select all of the vertices you want deleted. Either press “Shift + Del” or go to “Edit > Vertex > Delete Vertex” in PmxView.

The Facial Panel

If you only use premade motions, again, this is no issue. However, if you make your own motions… I’ll let you judge if this is an issue for you.

This part will not be as much laborious as it will be tedious. English names don’t matter at all, so you can name the morphs anything that will help you track them down and use them. To rename them, you just need to go to the “Morph” tab in PMX Editor and make sure the “EN” button is checked.

Have Fun With Your New MMD Models!

Hopefully this article opened some eyes about the possibilities of using VRoid Studio to make MMD models. While there aren’t many clothing or accessory options as of now, it is a lot easier than piecing together a model from parts on dA!
