Create and change 3D model expressions

Here, we will briefly explain how to create 3D model expressions created in Makehuman and imported into Blender.

I think that facial expression is very important to create realistic humanoid 3D.
No matter how detailed the model is made, it will be a mere 3D doll if you can not change the expression.
I think it is important to create facial expressions as to whether you can be satisfied with dolls or create models that are as human-like as possible.

The contents here must meet the following conditions.
1. The 3D model to be used has been created using Makehuman.
2. The created model should be exported to mhx2 and read into Blender by mhx2 importer.
3. Import face rig driver and face shape when importing into Blender by mhx2 importer.
4. Turn on automatic execution of Python scripts in your Blender preferences file.
5. Make sure you have installed the necessary plug-ins for both Makehuman and Blender.

These conditions are always required.

When these are ready
1. Of course, make a 3D model with Makehuman.
2. Export to mhx2 and import to Blender.
When importing, check [Override Exported Data] and make sure to check [Face Shape] and [Face Rig Drivers].
3. After importing, edit the model as usual.

It is a facial expression creation from here.
Use Face Units and Facial Shapes on the MHX2 Runtime tab of the tool shelf to create facial expressions.
* [Face Units] move the face bone to change the expression.
* [Facial Shapes] moves the mesh to change the expression.
* Insert keyframes using the right mouse button on each item.

4. It may be easier to make a blink first.
Open the upper eyelid-close the upper eyelid-open the upper eyelid
This will make you blink.
In my case, it is about every 50 frames.
Once you create the first blink, you can use dope sheet to copy and paste easily.
5. After that, create each expression using [Face Shape] and [Face Rig Drivers] at the required frame position.
6. Once you have an expression, you just have to animate.

One of my 3D models, [Rumi] is a facial expression test.
