How do you want to render hair? The renderer
you want to use affects what Output setting
you choose when you create hair. For more information, see
Hair Output and
Rendering Hair.
Do you want to include passive hair curves
in your hair system? See
Passive hair curves.
What kind of hair style to you want to
create? If short and simple, you can keep your Points
Per Hair (segments) low, but if you’re creating long
hair or a short, complex hairstyle you need more segments for flexible,
natural looking hair. Also, you can create multiple hair systems
on the same surface, which can be helpful if you’re adding bangs
(fringe) to a model. See
Assign a selection to a hair system.
