Enblend error: Mask is entirely black, but white image was not
identified as redundant

This is a well known "error" for enblend. Try to use the additional
enblend parameter "--fine-mask" to get rid of the error. The parameter
will result in generation of masks in higher resolution that will fix
the problem in most cases. Sometimes the "--fine-mask" parameter may
result in memory errors (malloc: ...), which are the result of not
enough memory available due to the (much) bigger masks that are used.

An alternative workaround would be to set the enblend --no-optimize
parameter, this will place the seam directly along the middle of the
image overlaps regardless of image content. This option is also
considerably faster and uses less memory.

This error also occurs when one photo is completely covered by another,
try removing redundant photos.

Note also that for the same reasons this error often appears when
rendering a scene with extreme distortion such as a stereographic
'little planet'. For this and other reasons, such as overall speed, it
is always preferable to render a 'normal' 360° Equirectangular
Projection panorama first, then load this as a single source image into
a new project and render whatever views you need.

Note (Jan 2010): This should be fixed in the latest enblend 4.0 release.

** Summary changed:

- sunset panorama crashes during "creat panorama" align tool works great though
+ enblend: mask is entirely black, but white image was not identified as redundant

Title:
  enblend: mask is entirely black, but white image was not identified as
  redundant

Status in Enblend:
  Invalid
Status in Hugin - Panorama Tools GUI:
  Invalid

Bug description:
  I was trying to create a sunset panoramic view from 9 images.  The
  Align tool worked great, I had a Good Fit.  I even went into Images
  and clicked "Create Control Points" under Feature Matching (Autopano)
  with the cpfind settings, 10 points per overlap.  After that, I
  clicked "clean control points" on the bottom of the right hand menu.
  I then aligned again, had a perfect preview, good fit, and clicked 3.
  Create Panorama...

  The screen came up, started working, then gave me the error message
  "Error during stitching.  Error during stitching, Please report the
  complete text to the bug tracker on https://bugs.launchpad.net/hugin.
  Do you want to save the log file?"

  I clicked yes, and here I am.
