it with the previous, cloned image. You can clone
the rendered fr a me window any number of times.
Enable Red Channel—Displays the red
channel of the rendered image. When turned off,
the red channel is not displayed.
Ena ble Gr een Channel—Displays the green
channel of the rendered image. When turned off,
the green channel is not displayed.
Enable B lue Channel—Displays the blue
channel of the rendered image. When turned off,
the blue channel is not displayed.
Display Alpha Channel—Displays the alpha
channel (page 3–1001)
.
Monochrome—Displays an 8-bit gr ayscale
of the rendered image.
Cle ar —Clears the image from the rendered
frame window.
Channel Displ ay L ist—Lists any channel rendered
with the image. When you choose a channel
from the list, it is d isplayed in the rendered frame
window.
For most kinds of files, only the RGB and alpha
channels are available. If you render an
RPF file
(page 3–681)
or RLA file (page 3–680) ,additional
channels can be present.
The rendered frame window displays nonvisual
channels, such as Material Effects or the G-Buffer,
using colors it randomly assigns to distinc t values.
Layer—This spinner appears on the rendered
frame window toolbar w hen you render to the
RPF
(page 3–681)
or RLA (page 3–680) file format. It
lets you see the information at different layers of
the following channels:
•Z-buffer
•Normal
•Non-ClampedColor
•Coverage
•NodeRenderID
•Color
•Sub-PixelWeight
•Sub-PixelMask
Layer shows no additional information for other
channels. It is useful primarily when the scene
contains objects that occlude each other, and you
have turned on the Render Occluded Objects
toggle for these objects. (See
Object Propert ies
(page 1–111)
.) Be aware that rendering occluded
objects increases render time.
Tip: Rendering occluded objects can help you

the Autodesk Combustion software.
Co lor Swatch—Stores the color value of the last
pixel you r ight-clicked. You can drag this color
swatch to other colo r swatches in the program.
Clicking the color swatch displays the
Color
Selector (page 1–157)
,whichdisplaysmore
information about the color.
You can leave the Color Selector displayed while
you right-click over other pixels in the rendered
frame window. (Changing the current value in the
Color Selector changes the color swatch on the
rendered frame window’s toolbar, but it does not
change the color of pixels in the rendered image.)
Frame-Steps (a r rows)—For sequentially numbered
files (such as
image0005.jpg) or IFL files, the
arrows display the next or the previous file in the
sequence. Holding down CTRL and clicking an
arrow jumps to the first image or the last image in
the s equence.
