Assign a selection to a hair system
Creating hair
Make curves dynamic
Select which UV set to use for Hair (polygons only)
Use UV sets to define where the hair
goes and to control its distribution and density.
By default Hair uses UV set map1, but you can
link your hair systems to different UV sets on your polygonal surface.
For example, if you have different UV sets defined for different
projections, you can link the hair systems to the UV set that gives
the best result.
In the Relationship Editor,
when you link a hair system to a UV set, all the hair systems attached
to the polygon are linked to that UV set. However the UV set is
controlled by the mapSetName attribute in the Extra
Attributes section in the
follicleShape,
so you could define it from there. (Currently you cannot edit the
follicle’s mapSetName attribute in the Attribute
Spreadsheet.)

TipCurrently you need to create a UV set for
hair that is between zero and 1. You can use regions outside this
range for areas you want to be bald. Or if you simply do not define
UVs for a triangle, then it will be bald. You should do this before
creating the hairs, as on creation of hair, hairs are rejected that
are located at undefined UV locations. If the UV for a follicle
becomes undefined after creation, then the follicle will simply
move to the center of the object; however, you could then manually
select and delete these follicles. See
Create your own hair on surfaces.
To
link attached hair systems to a different UV set
- Select
the object with the hair system(s) you want to link.
- Select
Window > Relationship Editors >
UV Linking > Hair/UV to open the Relationship Editor.
The left panel lists all the hair systems that
are attached to the selected polygon.
The right panel lists mesh nodes with UV Sets
for the selected polygon. If more than one polygon is selected,
only the last selected polygon is listed.
- In
the left panel, click a hair system. In the right panel the UV set
the Hair follicle is linked to becomes highlighted.
- In
the right panel, click the UV set you want to link the hair system
to.
