BandedColors is a sample net with a couple macros also in samples.
Therefore, there are Application Comments accessible from the Help Menu
within these nets.
I see that Band (and therefore BandedColors) requires 2D connectivity
(triangles or quads), but can't tell from the Object Description you
provide if the field is 2D or 3D (since you could have a 2D surface in a 3D
bounds box). So first be sure you are sending Band a "surface" not a
"volume".
But since the Field is Transformed, you've Scaled, Translated, or Rotated
upstream of the Band attempt. Try doing the Band before the transformation
to see if that helps. Transformations are only somewhat benign: some
modules just can't deal with them, so they are often best left to the last
operations before Image.
Also, substitute Color ("red") in place of the BandedColors and be sure you
are getting your object through as all red. You may simply have a Scaling
or Translation problem and the BandedObject is somewhere else in space than
in front of the camera. In Image, hit Ctrl-F to bring all current objects
into the camera view. If everything is way zoomed out, that's your problem
(you moved the BandedObject badly).
