Create Humanoid VRM

We will create a simple Humanoid VRM model.

After starting Blender, place the mouse cursor on the 3D Viewport and press the n key.

This will open a Sidebar from the right side. Select the VRM tab and click the Create VRM Model button.

Then an armature suitable for VRM output will be created automatically. An armature represents the bone structure of a 3D model. This add-on uses armature to represent the skeletal structure of the human figure in VRM.

We will use the default Cube as a torso.

Select the Cube in the 3D Viewport, select the tab with the “” icon in the lower right corner, go to Transform > Scale, and set all values to 0.2 to make it small enough to be used as a torso.

We associate the torso with the bones of the armature. Go to Relations, and set Parent to Armature, Parent Type to Bone, and Parent Bone to spine. The torso will move to the spine of the 3D model.

The next step is to create the head, press Shift + a in the 3D viewport to bring up an additional menu, select Mesh -> UV Sphere.

A Sphere will be added.

It is too big so we will shrink it.

Select the tab with the “” icon in the lower right corner, go to Transform > Scale, and set all values to 0.25.

Associate this sphere with the armature’s bone. Go to Relations, and set Parent to Armature, Parent Type to Bone, and Parent Bone to head. The sphere will move to the head of the 3D model.

Next, we will add the limbs: in the 3D viewport, press Shift + a to bring up the Add menu, and select Mesh -> Ico Sphere.

The Icosphere will be added, and at the same time, you will see > Add Ico Sphere in the lower-left corner of the 3D viewport. Click on this message.

You can then set up the new Ico Sphere to be added. We feel that the radius is too large so we will change the radius value to 0.1 m.

Select the tab with the “” icon in the lower right corner, go to Relations, set Parent to Armature, set Parent Type to Bone, and set Parent Bone to upper_arm.L. The sphere will move to the left upper arm of the 3D model.
