In this article, we will explain how to import VRM files into Blender.
If you are new to Blender, please read the following article first: https://styly.cc/ja/tips/blender-modeling-start1/
About Blender Versions
In this tutorial we will use Blender version 2.79.
At the time writing, version 2.8 is the latest. However, during testing importing a humanoid VRM file, version 2.8 couldn’t import anything but the bones.
We will update this content as soon as we discover what caused this problem in v2.8 version.
Import ‘VRM IMPORTER’
To begin, download VRM-IMPORTER from the following URL. This is for Blender v2.79.
You don’t need to decompress it; just leave it as a .zip file.
Open Blender and select ‘File > User Preferences’. Then, select the ‘Add-ons’ tab.
After opening the Add-ons tab, click the ‘Install Add-on from File…’ at the bottom.
This will open the file selection window. Select the VRM_IMPORTER (.zip file) downloaded earlier and press ‘Install Add-on from File’.
Return to the add-ons window and select ‘Testing’ to show ‘VRM_IMPORTER’ has successfully been imported (①). Check it (②) and click ‘Save User Setting’ (③). You can now close the ‘User Preferences’ window.
In Blender, select ‘File > Import’.
You will find that ‘VRM’ can now be selected.
Import your VRM file. It may take a little while, and occasionally Blender may freeze momentarily. Please be patient!
Note that, before importing a VRM file, it is recommended to create a folder and put in the VRM file you want to import, because many image files will be created in the directory where the selected VRM file is.
Adjust VRM Model
Have you imported your model successfully? It looks cute, right?
If your model looks ‘pale’, the display mode is likely set to ‘Solid’ or ‘Cycles Render’. You can fix this by changing it to ‘Material’ or ‘Blender Render’.
How to Change the Facial Expressions
Next we will demonstrate how to adjust facial expressions. When importing a VRM file its components will be sorted into groups by ‘hair’, ‘head and face’, ‘body and clothes’, and ‘bones’.
With the mesh of the face selected, you can change the facial expression by using ‘Shape Keys’ on the ‘Object data’ tab (①) in the right menu.
‘Shape Key’ is like a set of expressions. If you imported the VRM file created with VRoid, then some Shape Keys have already been set up.
As shown below, you can change the expression assigned to a Shape Key by selecting it and adjusting its parameters (more specifically, it defines the motion of the meshes for eyes, mouth, etc.).
How to Change the Pose
You can use ‘Pose Mode’ to change the pose.
Select a bone and press ‘Ctrl+Tab‘. The selection turns light blue.
This state is called ‘Pose Mode’, where you create poses by rotating and moving bones.
Export the Model
Once the pose is completed, let’s export the model with that pose.
Export the model as an FBX file instead of VRM, as FBX allows you to export the model with the pose.

You can also link Blender to Unity. Please refer to the following article: https://styly.cc/tips/blender-vrm-export2/（Coming soon）
If you want to animate the model, the following article shows how to add an animation.
Note that, when you add an animation to the model, export it in the way shown above (this is because VRM needs to be handled in a special way): https://styly.cc/ja/tips/blender-modeling-start6/
