A YouTuber has released an in-depth tutorial on making African hair.
A YouTube user Isaac Olander has released an extensive tutorial on how to make African hair in Maya XGen. Isaac comments that while working on the Dark Space: Part 2 - Unknown Lands project he found out that there were surprisingly few resources on creating African hair and a lot of experimenting needed to be done.
The tutorial is divided into 3 parts: Setting up XGen for a project, actual grooming, and the materials and tweaks Isaac made to make the hair look more realistic.
You can learn more about Isaac's art on the ArtStation page. There are many projects out there that can help aspiring Environment Artists get better.
