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.
