Hello!
Thanx.
The problem the stacking was: the hugin created only 23 stacks, after I change the stack size to 1, the result is much better.

btw, I dont have Optimalize tab. Its greyed out, as the Exposure tab.

thanx again

A good strategy might be first adding a few (4 per image pair) control points that tell hugin which window is which, then aligning preliminarily and telling hugin only then to add its 20 additional control points. One or two of then will be in the wrong place, again. But there is the "clean up control points" option for that.

Kind regards,

Gunter.

        Hi Csaba!

       Just an idea:  maybe you are using the "simple" interface, and
    this creates or tries to create new CP pairs before new alignment
    of (new) images? I am not sure, because I don't use this
    interface; I think it is intended for beginners and aiming to
    create a panorama "at once" from a given set of photos. And of
    course in your case you are feeding and growing an initial set of
    photos  (your # 3) , and starting a recipe meant to be run just
    once when you press align (#1) and this starts with "create CPs".

        I advise you to try at least the advanced interface.  In this
    case you will "align" only when you /optimize/ the panorama
    parameters, and this process does /not/ create new CPs. You will
    have to create the CPs beforehand, and you can improve or create
    yourself new CPs when desidered -- and they will take effect after
    a subsequent optimization.  A rule of thumb is optimization of
    'positions only', and when the result seemed OK (or almost), then
    you could include 'positions and visualization', etc.  For a
    correct 'visualization' optimization the panorama must be a
    complete turn around, and this is the case with your cylindricals.

       As for the stacks, I think some photos could have an excessive
    superposition and/or the same kind of image content and this could
    fool Hugin.

      Try please the advanced interface and tell us your progress. 
    Goof luck!

      regards,

      Luis Henrique

        Hello!
        My problems are:
        I have a large (100+) photo set for cylindrical projection.
        (for the whole rendering take 12+ hour)

         1. If I use the align button, it will always create new
            contol points. An because the image contains many block
            house always create point between wrong pairs. If I fix
            this, I cant preview it, because it say "need to align
            again". If I do, it will mess up again (and I need to
            check every 100+ image to searching the wrong pairs, It
            will be better to display a matrix, every cell how many cp
            for that pair)
         2. there are "stacks" in the result: many images in the same
            place, same orientation, and I dont know why, and how
            handle it.
         3. If I start with few images and add more, (and "align" it
            to see the result) I get error: there are two not linked
            group [0],[1-9] If i fix it, add new one, get more not
            linked groups: [0],[1],[2-10], and begin mess up (start
            rotate the first image)

        How can I "align" the images to see the result without the
        "align" button, or without the messing up?

        what I want to do:

         1. load every image, "align" it to see where need to fix.
         2. fix an error (add/remove cp-s, try to rotate, add
            horizontal lines etc)
         3. preview the result, if there is error: -> 2
         4. straigthen
         5. define the crop
         6. create the panorama

        Thanx

        orientation)
