And if more information is needed please let me know.


from the information you give I suspect that you suffer from a typical 
problem that beginners have: a large number of tutorials of which a 
certain number is completely outdated (our fault); and the urge to take 
all steps at once. Take your time and start with easier panoramas than 
one full spherical from a room.


Enblend was mentioned a few times in this thread. From having a look at 
your image I suspect you changed the blender to "internal" (verdandi), 
likely with the new "soft" option. Right?


Yes, we need more information from you:

About your camera / lens setup; do you use a pano head and tripod; have 
you understood and followed the steps to find the no parallax point 
(NPP) of your lens


What was your workflow:
- You seem to use JPGs, do you know about (is your camera capable of) 
shooting and working with RAW images? Your images btw suffer from color 
fringes which can be corrected during the whole process.
- Your file name ends with fused which tells me that you just clicked on 
some output option in the stitcher tab. Please describe your steps in 
Hugin, your computer platform, which version of Hugin do you use.

- Which user mode do you use (standard, advanced, expert)?

Did you already have a look at the tutorials section of the panotools 
wiki at ? It has some nice articles about 
first steps and basic concepts. You can also use it as a glossary for 
all the special terms used for this technique.


I always recommend not to start with a full spherical panorama taken in 
a room with lots of close features and complicated patterns at the floor 
and at the ceiling. Better go outside and look for a spot with some 
buildings around you. Take one complete horizontal row of images, all 
overlapping about 30% and covering the complete 360 degrees from left to 
right. This set of photos can be used to calibrate your lens (have a 
look at the wiki or use Hugins integrated help: search for "lens 
correction model" -> scroll down to "Determine lens correction"), check 
the quality of your panohead setup regarding the correct NPP, make 
yourself familiar with the concept of (look up ->) "vertical control 
points" (to align your panorama no matter if the tripod is set up in an 
exactly vertical position).


And please scale down panoramas you send to the list as some list 
members may use slow internet connections or check their mails on a 
mobile device. Better upload your image(s) to some online service and 
just send us the link.


You could send us your project file though (the one ending with .pto).

Cheers,
Carl

As Greg I also think I have seen this before. Did you use any mask? Did you
change the blender or any of its parameter?

Maybe you can also try to change the blender, like using multiblend.

No, look at the image.  The control points are OK.

Now that I doubt.  But it would be nice if you would send your
messages in plain text.

Hmm, interesting.  I've seen this kind of effect before, but I forget
why.  Could it be that you have used different exposures for each
image?  It could be that enblend is having difficulties adjusting the
exposure.

The other thing you could try would be a few more overlaps.
