Title:
  Mask rendering issue with full-frame fisheye lens for 360 pano

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  pto attached that highlights the problem.

  email sent to hugin-ptx yesterday:

  ===================================
  Hi there!

  I'm experiencing a very weird behavior in hugin 2011.2.0 on a gentoo
  64 box. I have a 360 pano of 15 shots taken with a full frame fisheye
  10.5mm. There are so many shots because I am doing a clone photography
  experiment of the same subject several times in the pano.

  I've set up masks accordingly to include the subject in all relevant
  shots. masks do not overlap accross shots.

  For 2 of the shots, where the subject is roughly 180 degree from
  himself, enabling both pics at the same time with masks gives me a
  completely wrong masking result (both in hugin and as exported by nona
  on stitching).

  I have a taken a few screenshots showing the problem here:
  http://timotheegroleau.com/bugs/20111116_hugin_mask/

  note the incorrect render when both pics are activated simultaneously.

  Has anyone experienced this before? How can I troubleshoot and fix
  this?

  Thanks in advance!
  Tim

  ===================================
  Yes we have seen and fixed similar bugs with masks and fisheye
  photos before.  The workaround is to just edit the mask and move
  some nodes, the problem should go away.

  ..but before you do that please save the .pto file and attach it to a
  bug report on launchpad: https://bugs.launchpad.net/hugin/+filebug

  I have tried to edit the masks to be as close as possible to the subjects outline, I can't get the problem to go away :(
