What is Random Head Generator:

It is a framework to make decent looking human head FAST. It utilizes Blender's shapekey system and categorizes the creation process into small tasks of different aspect. By randomizing shapekeys' value, it generates unique human head at a single click.

The Goal: Expandability and Reusability

It often takes hours to create heads. Instead of start from scratch, build upon a base head and re-use any previous work will greatly expedite the creation process. Made an unique looking face? Use the semi-automatic process to append it to source file, expand the randomness pool and re-use it next time.

The Not:

Personally, the base head is intended for real-time application such as game engines. Although the mesh is good enough for general usage, each project may require some modification. Please check here to see model details. The base mesh is around 4k triangles. Shapekeys are created at 65k triangles. The primary focus is head shape variety, other included assets are NOT, such as textures. Generally, I would add personal touch afterward, for example, add makeup, dirt, scar etc. in 3rd party painter.

The Content:

It has 100+ ready to use shapekeys, including general head shape

different head part such as eye, ear, mouth, nose, forehead, cheek and jaw

common features like age, weight

ready to use face templates

as well as emotions

It has two set of hairs for quick visualization:

and 4k unlit PBR textures ( albedo, normal, roughness) (pale, yellow, dark skin tone) for texture painting.

The Bonus:

Ability to append 51 ARkit shapekeys to final head mesh with ease. Proper Apple hardware (iPhone X and above with faceID) and facial capture software (Unreal live link face) are required. more info about ARKit blendshapes here

PS:

For advanced users, if you'd like to incorporate your own mesh, head over to document section for more detailed how-to.

WARNNING: before updating, I recommend keep a copy of your blend file. the default addon path is: C:\Users\Username\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\RandomHeadGen

if you have added your own blendshapes, download the "Addition.blend" file from your download page and copy it to the addon path mentioned above. open "RHG_HeadMeshFile.blend" and scroll down inside adjustment panel and press "Append Additional Shapekey", this will add those new faces in source file for future usage.

otherwise, the version 1.0.2 zip file contains all new additions, you can update it old fashion way.

Update 1.0.1:

Added function to append new shapekeys in source blend file.

this operator only available when open source blend file "RHG_HeadMeshFile". it is located at the very bottom "Append Additional Shapekeys":

this will append any new shapekeys from mesh named "Addition" in a "Addition" collection of blend file named "Addition". It paves the way for future shapes appending.
