• Ma p Channel—Choose this to p aint on a
specifically named or numbered map channel.
Ma p channel s pinner—Specifies the channel
number. Available only when Map Channel is
chosen.
Note: Ifyouhavepaintedonalayerandthenchange
the channel setting, the p ainted information will
be moved to the new channel. For example if you
select Vertex Color and paint, then turn on Vertex
Illum, the painted infor mation will be removed
from the Vertex Color channel and applied to the
Vertex Illum channel instead.
Name—If a channel has a name defined it will
appear here. Channels can be named using the
Channel Info Utility (page 2–1738) .
Ignore und erly ing color—When tur ned on,
VertexPaint ignores whatever vertex colors it
receives from below it on the stack. As a result,
you will see the layer’s raw colors on an otherw ise
whiteobject.Theblendmodehasnoeffect(it
behaves like Normal mode) because the base
color is considered transparent, so the la yer is not
blended with anything.

from the colors below, to help the user visualize
the layer’s raw data. The layer is not completed
isolated w h en this is on, because layers above it
can still affect the result. The user needs to disable
those layers or turn off Show End Result to see the
current layer in complete isolation.
The Ignore Base Color toggle should only be
needed when the object at the bottom of the
stack already has some vertex colors baked in. In
other cases, you can just disable the paint layers
or whichever modifiers are adding vertex colors
to the object. In that case, the active paint layer
would not receive an y vertex colors from below
itself on the stack. As a result, it treats all base color
as transparent and the layer colors are displayed in
the raw (not blended with anything).
Note: Per-vertex layer opacity is not passed up
the stack. A paint layer modifier makes a yes/no
decision about whether an object below it has
vertex colors or not, and will subsequently t reat
allbasecolorsastransparentorallasopaque.
So if you paint even a single vertex using Edit
Mesh, for example, the object is considered to have
vertex colors, and a paint layer wi ll blend its colors
w ith the (predominantly white) mesh instead of
treating the mesh as transparent.
Preserv e L ayer —When on, the modifier will not
be deleted by any Condense To Single Layer
operation. SinceCondenseToSingleLayer
performs two independent actions (creating a new
baked-color modifier and then deleting existing
modifiers), this option allows access to only the
firstpartofthefunctionalitywhennecessary.
That is, you can bake colors into a new paint layer ,
without being forced to have the old modifiers
deleted.
Edit—Displays the Ve r tex Pa int b ox f l o ater ( p a ge
1–941) if it has b een closed.
