I'm having a problem with the alignment tool, I've done this before with a hard object whereby I take my photos, turn it upside down, take some more, and I can cut the dense cloud in two 2/3rds for each chunk and then photoscan can align the two to have a completely scanned model. But I went out into the woods and tried this with a few logs; I took my photos, turned each log over and took some more but now this has not worked in terms of merging these two chunks on 2/3 of these so far. I can guess why, what with the little differences when I turn it over and say, a leaf might get stuck on the log I didn't spot. Or at least that's my guess, but I wish the program had a bit more leniency in this way
