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.
Personally, the base head is intended for real-time application such as game engines. It may NOT fit your project requirements, such as mesh density, polycount etc. Please check here for model details. The base mesh is around 5k vertices (10k triangles). Shapekeys are created at one subdivision up at 19k vertices(39k triangles). You can subdivide up and sculpt details but lower than base mesh, manual modification is needed. 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.
It has 127 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.
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
For advanced users, if you'd like to incorporate your own mesh, head over to document section for more detailed how-to.
fixed file path error for Mac OS users.
added 6 new face templates.
minor script tweak.
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.
Added two nose controls: nose size, nose up down.
Added 5 more face templates.
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.
