I made this very basic tutorial to give a little help on how to make Mesh Heads.
In particular, this one is for my Jenna V2 Mesh Head available here

The AI face generation website I have used in the video is here if you wish to follow the tutorial

Please be aware, I am not a texture artist, this is very basic, but shows the concept in practice of how to generate a mesh head texture, and steps to blend it to the skin underneath. I am NOT a painter..
Don't hate me.
