Room Capture Only using 4 images of 300 In Image alignment.

Erik Kubiňan CR That doesnt seem to be the case for me. One of my runs it managed to get about 200 of the photos and add tie points. Then I hit align photos again and i was back to only 5 photos with tie points.

 

Is there anyway to tell it which photots to start from when alligning images or does it chose images by random?
