 Get
yourself a model that needs some hair. Render
him out using BEST RENDER in the RENDER panel with whatever light/material/shadow
settings you need for your scene. Once the scene is rendered go
to the LAYERS panel and hit the BAKE button.
Now
go over to the TOOL panel and locate the
FIBER BRUSH from the popup menu
Now
to see how NOT TO DO IT just draw a stroke across the head without
adjusting any settings. The result is a solid mass of dense hair
that looks out of place.
To
change the look of the FIBER brush hair there are a number things
we can do. First is to change the Material to FLAT.
Then
lower the RGB INTENSITY and the Z INTENSITY
a little: experiment to achieve the desired effect. Vary the DRAW
size to lengthen the strands as needed. Small DRAW size = short
hair. All sorts of effects can be achieved with just these three
before we even start to edit the FIBER BRUSH settings. If you are
using a graphic tablet you will see that the FIBER brush is pressure
sensitive, more pressure, more hair.
Next,
go to the TOOL PANEL and take a look at the settings in the FIBRE
BRUSH panel. Most of these are self explanatory and if you hold
down CTRL whilst hovering over the item ZBrush will tell you what
it does anyway:
 Armed
with the above info you can set about spraying hair onto just about
anyone or anything in ZBrush.
