Maya XGen HairStyle LABO 
I am creating a general-purpose “hairstyle library” that can be used for both movies and games. The diagram above shows the work path.
None of the sites had libraries or documentation, and I questioned the inefficiency of having to create hairstyles from scratch every time.
I am developing this on my own, hoping that this initiative will help increase productivity. Explanatory tips will also be provided on this site.
The reason I chose Xgen was because it provides peace of mind with its standard features of physics calculation and rendering, and the ability to output directly to MetaHuman (Unreal Engine).
