Big difference between Lightroom and PTGui stitches. Lightroom stitch much better here.

Hi,
I am recreating some panoramas in PTGui that I had previously created in Lightroom. For most of the panoramas, the results are much better in PTGui. However, I have a particular panorama here that consists of 7 images and PTGui seems to be causing major problems. I have attached photos here that prove this. In the version from Lightroom everything is OK so far and I can be seen in all seven places in the panorama correctly and without losses. With the panorama from PTGui it looks completely different. In three places I have been cut and parts of my clothes/shoes/backpack are missing. The sky was also calculated very uncleanly, which you can see very well in the direct comparison. I don't know how I can change this in PTGui, because the hems are fixed. Does PTGui perhaps have a problem because I am not in the center of the image on all seven shots? In this context, I find it very interesting that Photoshop can't do this at all and the result is even worse than in PTGui.
Thank you for your help.
Kind regards
Frank

In the pro version PTGui would either route around the objects
automatically using optimum seam placement, or you could use masks to
include or exclude certain parts of the images.
In the standard version you would need to mask the images in an external
application using alpha channels, such that the the area where parts are
missing are masked in the other image(s). This will force PTGui to place
the seam elsewhere. Or you could use an external blender (like f.e.
enblend) which also has the ability to route seams around objects.

Did you actually create the panorama? The screenshot is from pano editor
in show seams mode, where no blending takes place. Switch to blended
mode to get a better preview.
It seems the two rightmost images are much darker than the others. This
can probably be corrected using exposure correction. See Exposure tab.

Hi Erik,
Your answer was very helpful and I've quickly updated to the pro version and now it works fine.
Thank you very much.
Frank
