Hello jerry,

Probably there are too little number of feature points found on the object after adding the masks.

If you wish we can check the data in case it can be provided - please contact support@agisoft.ru.

use mask, and select PAIR PRESELECTION and set GENERIC.... it should work....

Sometimes it?s a good idea to use two chunks when processing an object that needs to be turned upside down by hand. I printed out some very small markers that I use for alignment reasons. Works very well for me, probably you give it a try If you need a textures model you can take extra-texture-photos without these markers and use them for texturing.
