[Blender Add-on] Creating Virtual Humans with HumGen3D (1) “How to install and set up the human body”

For those of you who want to use original virtual humans in Unity or STYLY, this is a good news article!
I found a paid add-on that allows you to make them in Blender.

A similar software is Daz3D, which I have written about before.

This time, HumGen3D is an add-on for Belnder, so once you download and install it, you can complete your work using only Blender.

Let’s use HumGen3D to create some virtual humans!

The version of Blender used in this article is 2.92.

What is a virtual human?

Virtual humans have been featured in various advertisements lately, so I’m sure many of you have seen them or know about them.

A virtual human is a “non-existent person” made with computer graphics.

They are so real and unique that they are indistinguishable from real people, and even though they are virtual, they blend in with the real world and use social networking sites just like us.

Download and install HumGen3D

You can download it from here.

Open Preferences from the top left icon of Blennder.

Click “Install”, and install only one zip named HumGen3D_V1_01.zip in the one you just downloaded.

Check the installed add-on, and the screen will change as shown below.

Click on the blue “Select Folder” button and choose where you want to save the HumGen content pack.
Note that you need to have 1GB of free space.
I specified the downloaded zip folder for clarity.

After that, click “Install All Content Packs”, select the ZIPs you just downloaded (four ZIPs starting with HG_CP), and install them.

And finally, click “Install all content packs” to complete the entire installation.
Let’s try it out right away!

You can use the 3D Viewport from the menu on the right side of the main screen.

If you don’t see it, click < to bring up the menu.

When you click the Get Started button, the screen will look like this and the tutorial will be displayed.

You can view this tutorial again from the Extras section.

Installing on a Mac

As of May 2021, there is a problem with the textures not showing up when used on a Mac.
Please contact HumGen3D and they will send you a revised version.

Creating a Face: Advanced Settings

You can edit not only the shape of the face, but also various other settings.

• Shaders: Allows you to set skin wrinkles and subsurface scattering.
  Subsurface scattering is a material that recreates a transparent object and can be used to represent realistic human skin.
  It is best to set this last, as it takes a long time to process and can cause slowdown and noise.
• Eyes: Changes the color of the eyes and whites of the eyes.
• Dark/Light areas: Adjusts the dark/light areas of the skin.
• Freckles: Add freckles or edit the amount.
• Beauty spots: Add or edit the amount of moles.
  Use “Seed” to change them randomly.
• Age: Adjusts sagging and wrinkles of the skin.
• Beard shadow: Add shave marks.
