The chunk info says that they are all aligned?  The order is weird. There seems to be two of each and they go up from 0 to 1 to 10 to number 19, then number 2

Hello Brit,

The order of images in the Workspace pane doesn't matter.

Best regards,

I aligned it again removing the second set and got this.

1. Align the photo, dense cloud and build the mesh without any masking
2. The generated mesh is roughly formed

3. Now, select the import mask -> from model! you can see the photos are masked with the rough model but not very fine

This is the part I am unclear about - in order to import masks, I need to have masked all the photos in advance. I though that this method was to avoid making detailed masks? Do you mean > mask the images, then import and build cloud and mesh without the masks first? And then import the detailed masks?

4. Then you can check the photo and edit the mask of each photo manually.

How do I edit masks once they are imported (and the mesh is already made)?

Masks are created, not imported, for each photo based on the existing model when the "from model" option is selected for "Import Masks".

I only mask when the background has changes or moves between photos. My experience is a person walking through or a car driving through which only appear on one or two photos do not cause any problems. Also I have not had problems if an object is present in the background but stationary for some of the photos and completely out of other photos with similar alignment.

A stationary background can help alignment.

In theory, the order of images shouldn't matter but I'd suggest renaming images anyway so that the number at the end has the same number of digits and windows sorts correctly. Yours are sorting alpha numerically (left to right) so 1, 10, 100 and 1000 all come before 2. I have experienced similar outcomes in the same situation (but not always), and having the images in the right order can help.

We use Adobe Bridge because it sorts the files correctly with the shorter names and has a nice batch naming tool.
You just need to use a filename that has the same number of digits for all of the numbers, using leading zeros to make them the same length.

file1 > file001
file10 > file010 etc

If you've got less than 100 images then it's just as easy to manually rename images 1-9 with an additional 0 in front of the number
