The Selection rollout
provides tools for accessing different sub-object levels and display
settings and for creating and modifying selections, and displays
information about selected entities.
When you first apply
the Hair And Fur modifier to an object, the entire object is affected
by the modifier. You can specify that the only part of an object
should grow hair by accessing a sub-object level and making a selection.
Clicking a button here
is the same as choosing a sub-object level in the modifier stack
display. Click the button again to turn it off and return to the
Object selection level.
NoteControls on this
rollout are available only when the growth object is a mesh. If
the growth object is a spline, the Selection controls have no effect,
and sub-object levels for the Hair And Fur modifier are not visible
in the modifier stack.
Accesses the Guides sub-object
level, which lets you edit the styling guides using tools on the
rollout. When you click Guides, the Style
Hair button on the Styling rollout is automatically turned on, and
Accesses the Face sub-object
level, which lets you select a triangular face beneath the cursor;
region selection selects multiple triangular faces within the region.
Accesses the Polygon sub-object
level, which lets you select polygons beneath the cursor. Region
selection selects multiple polygons within the region.
Accesses the Element sub-object
level, which lets you select all contiguous polygons in an object
by clicking once. Region selection lets you select multiple elements.
- By Vertex
When on, you can select a
sub-object only by selecting a vertex that it uses. When you click
a vertex, all sub-objects that use the selected vertex are selected.
- Ignore Backfacing
When on, using the mouse
to select sub-objects affects only those facing you. When off (the
default), you can select any sub-objects under the mouse cursor, regardless
of their visibility or facing. If there are more than one sub-object
under the cursor, repeated clicking cycles through them. Likewise, with
Ignore Backfacing off, region selection includes all sub-objects,
regardless of the direction they face.
NoteThe state of the
Backface Cull setting on the Display panel does not affect sub-object
selection. Thus, if Ignore Backfacing is off, you can still select
sub-objects, even if you can't see them.
Named Selection Set group
Places a named selection into
the copy buffer.
Pastes a named selection from
the copy buffer.
TipYou can use this
to grow hair from an existing selection lower on the stack. However, because
the Hair And Fur modifier outputs an editable mesh, the copied sub-object
selection should be from a mesh-based modifier. For example, if
your base object is an editable poly, you can use tools such as
Ring, Loop, and Grow to make a procedural edge selection, and then Ctrl+click the Polygon button on
the Selection rollout to convert the selection to polygons. Next,
apply a Mesh Select modifier (not Poly
Select), and go to the Polygon sub-object level; the Mesh Select
modifier inherits the Editable Poly selection. Use the Named Selection
Sets field on the main toolbar to name the selection, and then use
the Mesh Select modifier's Copy function on the named selection. Finally,
apply the Hair And Fur modifier, go to the Poly sub-object level,
and paste the selection.
- Update Selection
Recalculates the area from
which hair is grown, based on the current sub-object selection,
and refreshes the display.
When you access a sub-object
level within the Hair modifier and make a selection, the area of
hair growth doesn't automatically update. Click Update Selection
to view the results of a change in sub-object selection.
