>From your description I conclude that you have left hugin in its default mode (Interface -> Simple). I doubt that this mode is sufficient for the type of panorama you want to achieve. Please switch to expert mode and create a new project. Then use the "Add images .." button to add your images to the project. The next step would be to set the stack size. Right-click into the list of images and select Stacks -> Set stacks size. Here, you have to set the "Link positions of each image in Stack", too: If your images were shot on a sturdy tripod and you are sure that the stacks do not need additional alignment, you can set this tick mark, otherwise remove it. Next step is to create control points. However, I assume that Hugin's CPFind somehow takes the lens type into account, at least I get much better results for my samyang images when setting the lens type to Stereogrphich instead of the default Normal (rectilinear). I have no idea what lens type you used, so you may have to google this or experiment with the various options. In any case, make sure you select all the images and then set the lens type properly if it is not set so already. Clicking on "Create control points" finishes this step. Now it would be a good time to save your project. I normally then move to the Optimize step. First, I do "Positions (incremental, starting from anchor)", then "Positions and view (y,p,r,v)". This would be another good point in time to save your project, by the way. Afterwards, I do a first rough pruning of the control points. For this, I press F3, then "Select by distance" and accept whatever Hugin suggests. Pressing the delete key gets rid of the control points that lay outside of the value chosen. I may have to repeat the Align and Delete steps a couple of times until the maximum distance is below 5 or 2, or 10, or .. This really depends on the quality of the shots and the number of control pints I get. You will need to leave enough control points so all your images stay connected, but the more outliers you can eliminate, the better the panorama will turn out. Afterwards, I set the geometric optimization to "Everything without translation" and repeat the optimizing and pruning until the maxiumun distance is below 1.0. Next step would be to run the Photometric optimizer. When doing HDR, one of the "High dynamic range" settings is recommended. If this is not a full sphere panorama, some fiddling with output projection type, centring, fitting, straightening and cropping is required next. Then, we switch to the stitcher tab and define the output image type we would lie to get. Press Stitch! and enjoy! Clicking align always > leaves out at least one image. I can not comment on this as I never use simple mode. However, the last image just may not get any control points, so it is being ignored by hugin.

Can you provide a link to the tiffs and the pto somewhere so we can have a look? > http://pasteall.org/pic/index.php?id=112888 This I can not diagnose, I suppose a developer with windows development tools may be able to do so, Again, if the pto and the images would available, this would be helpful. > > I noticed that I can drag images by clicking on the sphere.

Dragging images around in a botched pto can lead to severe geometrical problems that may not be handled properly because nobody tested this specific situation. And I have never been able to get a proper panorama when trying to move images around. > > > ***Problem 2:* > Alignment doesn't work.

If the lens type in your project does not match the physical lens type, things like this can happen. Additionally, for an algorithm, it is very hard to find control points in images mostly containing snow. But without being able to have a vclose look at the images and the ptos, this is ll speculation. > If project watered down to 6 images in cylindrical projection with no > stacks still no effect. > Does drag/move tab have any relevance for finding control points?
