Convert SFM/GMOD Models Into MMD Flawlessly!

How do I convert SFM/GMOD models to MMD?
From where do I get SFM/GMOD models?

Is it possible to edit converted SFM/GMOD models in PMXEditor?


Do you ever see a pretty model that is for SFM or GMOD and wish that it was for MMD? Well, look no further! In this article, I will explain everything you have to do to get your dream models into MMD! This is a really long process so please stay focused.

Convert SFM/GMOD Models Into MMD Flawlessly!

First, you need to download the following programs (See your computer’s OS properties to download the correct program):

Blender 2.79
MMD Tools
Source Tools

Step 1: Applying MMD Tools and Source Tools to Blender.

After you download and install Blender on your computer:

1. Open Blender.
2. Go to [File>User Preferences].
3. At the bottom, click on [Install Add-on from File].
4. Go to the folder where MMD tools is located then click on its ZIP/RAR file to install the add-on, do the same for Source Tools.
5. In the User Preferences window, search for “MMD Tools” and “Source Tools” then check the boxes next to them. 

Step 2: Downloading the models.

Two sites I prefer for downloading models the non-Steam way is and SFMLab. You can also download models through the Steam Workshop Downloader website to download models only available on Steam.

  • Method for SFM/GMOD Models downloaded through SFMLab/

1. Download the model.
2. Unzip the file.

You’ll have two folders: “models” and “materials”. The “models” folder has files that have the extensions (.mdl), (.vvd), (.phy), and (.vtx). We don’t need the VVD, the PHY, and the VTX files because they are additional data that work only in SFM and GMOD so you can delete them. We must focus on the MDL file. That’s the model’s data, similar to PMX and PMD but MDL files are compressed and need decompiling or decompression.

The “materials” folder has files that have the extensions (.vmt) and (.vtf) which stand for “Valve Material File” and “Valve Texture File” which can be opened using VTFEdit. VMT files are code so you can delete them. VTF files have the textures in image file formats which are what we need.

The method for SFM models downloaded through the Steam Workshop Downloader is the same. 

  • Method for GMOD Models downloaded through the Steam Workshop Downloader:

When the download is finished, you’ll have a file that has the extension (.gma). Rename it to a simpler name (Ex: NameHere.gma) then decompress by doing the following:

1. Open GWTool.
2. Drag the GMA file into the GWTool window.

The program will extract the GMA file into a (.7z) file.

3. Extract the 7z file with 7-Zip.

The 7-Zip file will extract a ZIP file. Decompressed it with 7-Zip. You’ll have the two folders: “models” and “materials”.

Step 3: Decompiling the MDL files.

Go to the “models” folder and do the following:

1. Open Crowbar.
2. Go to the decompile tab.
3. Drag the MDL file into the program window.
4. Choose an output folder and uncheck the following settings:

  • Physics mesh SMD file
  • Bone animation SMD files

In the output folder, a bunch of files will be extracted. Most of them have the extension (.smd) and one file has the extension (.qc).

The SMD files are the model separated into multiple parts or assets. This is very helpful if you only want a part of the model. The QC file is the complete model unseparated, that’s the one we need.

Step 4: Decompressing the VTF files.

After you complete decompressing the MDL files, you have to extract the textures. This is where VTFEdit comes into play. After you download and install VTFEdit, go to the “materials” and do the following:

1. Open VTFEdit.
2. Drag the VTF file into the VTFEdit window.
3. Make a folder for the textures, I’ll call mine “Tex”, and save the textures in the folder either as a TGA file or a PNG file to keep transparency.

Step 5: Converting the models to PMX format.

Now you have to convert the model to PMX format by using Blender, MMD Tools, and Source Tools.

1. Open Blender.
2. Go to [File>Import].
3. Look for [Source Engine (.smd, .vta, .dmx, .qc)] and click on it.
4. Look for the model’s QC file and import it into Blender.

There are multiple tabs on the left. If you have installed MMD Tools correctly, you’ll see a tab titled “MMD”.

5. Click on the MMD tab.
6. If your model has bones (the small spheres on the model) then click “Convert” to convert the bones to the MMD bone format. If your model doesn’t have any bones, then click “Create”.
7. Click “Attach meshes to model”.
8. Go to [File>Export] and look for [MikuMikuDance Model (.pmx)] then click on it.
9. Look for a folder to save your model.

Step 6: Editing the models in PMXEditor. (Applying Textures and fixing minor errors)

Although you did convert the model to PMX format, there are still some errors. Some are the model is too large and the model is missing textures. Here’s how you fix these errors:

  • Fixing size:

1. Open PMXEditor.
2. Drag model in PMXEditor window.
3. In “Add/Scale” window, go to the lower right part of the window and write 0.3 in the box next to the word “Custom”.

0.3 is the normal size for most SFM/GMOD models to fit the MMD height. But you can resize it as much as you want!

  • Applying textures:

1. In the materials tab, select all the model parts and change “Diffuse” and “Ambient” color boxes to white and the “Specular” color box to black.
2. Normally, the textures are named the same as the model parts. So find the texture that has the same name as the model part.
3. Add/Edit some extra things to the model to your liking. Such as adding morphs, adding toon or spheres, re-rigging some parts, or connecting bones to each other.

That’s it! You have your model ready for MMD!
