Select face —Allows you to select faces in
the c urrently selected objects. Once selected, only
these faces will be available for painting.
Sel ect element —Allows you to select
elements in the currently sele cted objects. Once
selected, only these elements will be available for
painting.
Ignore Backfacin g—When this is on, prevents you
from mistakenly selecting sub-objects facing away
from the user.
Soft S election—The same soft-selection options
(page 1–963) found in Editable Mesh and Editable
Poly are available by clicking this button.

B lur A mount spi nner—Blurs currently selected
channel values (for example, vertex color, alpha)
for the currently selected objects. Also supports
sub-object select ion of vertices, faces, and
elements. With soft selec tions, the fi nal blurred
value is computed, and then combined with the
original color according the selection; a 50 percen t
soft selection means that a vertex will become a
fifty-fifty combination of its original color and
the blurred color. Successive clicks of the Blur
button will succesively blur the previous results,
eventually washing out painting effects entirely.
Blur is useful for softening vertex color lighting
information that is automatically generated by
the Assign Vertex Color utility or rollout. Assign
Vertex Color computes intensities per vertex. This
is especially useful for low-resolution geometry
and hig h-frequency lighting changes.
Blur Brush—Lets you apply
blurring by us ing the same br ush techniques and
settings that you use to apply color. The Blur Brush
respects sub-object selection and the Blur Strength
setting.
Layers group
Mode—The layer mode drop-down list allows you
to select a specific operator for this paint layer.
The operator selected affects base color, alpha,
illumination, and other information coming up
from layers below it, or from the b ase objec t itself.

color is combined with any newly painted colors
for the current level.
This mode is changeable at any time, without
