In this article, I will show how to import VRM file into Blender.
If you are new to Blender, please read the following article, too.
About Blender versions
In this tutorial, I use Blender version 2.79.
As of this writing, version 2.8 is the latest, but, when I actually imported a humanoid VRM file, version 2.8 couldn’t import anything but the bones.
…Perhaps it (this VRM file) was ‘alive’ just in the ‘v2.79’ era and ‘passed away’ before v2.8 arrived…
It’s now unexpectedly summoned to the ‘v2.8’ future, so it came with what it should look, that is, its ‘remains’, I imagine…
Nothing is permanent, isn’t it?
Anyway, I will give you the update as soon as I find what caused this problem.
Import ‘VRM IMPORTER’
Firstly, download VRM-IMPORTER from the following URL. It’s for Blender v2.79.
You don’t need to uncompress it. Just leave it as .zip file.
Open Blender and select ‘File > Use Preference’. Then, select the Add-ons tab.
After opening the Add-ons tab, press the ‘Install Add-on from File…’ at the bottom.
It opens the file selection window, so select VRM_IMPORTER (.zip file) downloaded earlier and press ‘Install Add-on from File’.
After returning to the add-ons window, select ‘Testing’ to show ‘VRM_IMPORTER’ imported earlier (①). Check it (②) and press ‘Save User Setting’ (③). Now you can close the ‘User Preference’ window.
In Blender, select ‘File > Import’.
Now you will find ‘VRM’ selectable.
Import your VRM file. It could take a while or, sometimes, shut down Blender. 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 set to ‘Solid’ or ‘Cycles Render’. So, change it to ‘Material’ or ‘Blender Render’.
How to change the facial expressions
Firstly, l will show how to adjust facial expressions. When importing a VRM file, it’s sorted into the groups, ‘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) of the right menu.
‘Shape Key’ is like a set of expressions. If you imported the VRM file created with VRoid, 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 (Precisely, it defines the motions of the meshes for eyes, mouth etc).
How to change the pose
You use ‘Pose Mode’ to change the pose.
Select a bone and press ‘Ctrl+Tab‘. Then, 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 FBX instead of VRM. In this way, you can export the model with the pose.
Please read the following article to learn how to export and upload to STYLY.
There is a way to link Blender to Unity. Please refer to the following article.
If you want to animate the model, the following article shows how to add an animation.
Note that, when you added an animation to the model, export it in the way shown above (This is because VRM needs to be handled in a special way).
Please read the following article to add accessories etc. to VRM model.
