Break (B)—
Separates a ll selected, unified normals
into their original components. With Unif y/Break
To Average off, Break orients each separated
normal perpendicular to its respective face, thus
splaying out the normals at each vertex if the
connected faces are at different angles (as with a
sphere). With Unify/Break To Average on, each
separated normal uses the orientation of the
original normal.
Break converts any selected normals to specified
normals.
Unify/B reak to Average—Determines normal
orientation as the result of a Unify or Break
operation. See the descriptions above for details.
Default=off.
Average group
These controls give you different methods of
averaging vertex normals; that is, setting them all
tothesameabsoluteangle,whichistheaverageof
their combined angles.
Selected—Sets selec ted normals to the same
absolute angle: the average angle of a ll of them. If
Use T hreshold is on, averages only normals whose
distance from each other is less than that specified
in the Average Threshold spinner (to the button’s
right).
Use T hr eshold—Activates the Average
Threshold setting, and causes the S elected to
averageonlynormalswhosedistancefromeach
otherislessthanthespecifiedvalue.
Target—Enters an interactive mode in which
you specify pairs of normals to average. Click
Target, and then select a norm a l. When the mouse
cursor is over a normal, it changes to a + cursor.
After clicking the first normal, a rubber-band
dashed line connects the normal to the mouse
cursor. Click a second normal to average the
angles of the two normals.
The pixels spinner to the rig ht of the Target
button sets the maximum distance in screen pixels
between the mouse cursor and the target normal.
Copy Value (CTRL+C)—Copies the selected normal’s
orientation to the copy buffer. Available only when
asinglenormalisselected.
Use Copy Value and Paste Value to apply a
normal’s orientation to one or more others within
thesameEditNormalsmodifier.Youcannotcopy
normals b etween modifiers.
Pas t e V al ue ( CT RL +V)—Applies the paste buffer
contents to the current selection. Available only
after Copy Value has been used to place a normal’s
orientation in the copy, and one or more target
normals are selected.
Specify (S)—Converts selected normals to specified
normals
.
Reset (R)—Causes all selected normals to revert
to
unspecified status, and returns them to t heir
initi al, calculated positions. Also breaks apart
unified normals.
Mak e Explicit (E)—Converts selected normals to
explicit normals .
[S election D is pla y] —When one normal is selected,
shows its ID number. When 0 or more than one
normal is selected, shows the number of normals
selected.
