Control (UI) Default Value Function
channels Input Selects the channels to render:
• RGBA - Render the red, green, blue, and alpha
channels. If any of the color channels are missing
from the input, they are filled with 0 (pure black). If
the alpha channel is missing, it is filled with 1 (pure
white or fully opaque).
• RGB - Render the red, green, and blue channels. If
any of these channels are missing from the input,
they are filled with 0 (pure black).
• A - Only render the alpha channel. If this channel is
missing from the input, it is filled with 1 (pure white
or fully opaque).
• Input - Render all channels that exist in the input. If
the file format does not support the input channel
configuration, required but missing channels are
filled with 0 (color channels) or 1 (alpha).
rawData disabled When enabled, Katana skips the automatic colorspace
conversion (that is, the conversion from its native
linear floating-point format to the output colorspace).
colorConvert enabled When enabled, Katana converts rendered image data
from its native linear colorspace to the output
colorspace specified in the file name. This is desirable
in nearly every situation.
A case where you would want to set this to disabled is
if you know the data being rendered is in a colorspace
other than linear (such as the re-projection of a log
plate) and you want to name the output file log
without a linear to log conversion.
