Hi Alexey,
I have another suggestion for Agisoft Photoscan. Would it be possible to think about the addition of a Batch "Automatic Colour Key" tool for masking and cutting.
Say you have 10-20 photographs, with a well lit Chroma Key Background, Green, Blue, White or Black etc. Being able to use a "Color Picker" to choose which colour you want Auto Masking to mask. Choose your colour and it cycles through the images in Agisoft, masking them. Then at the end of the build it auto cuts away those masked areas when using Object type: Arbitrary and Geometry type: Smooth.
This would be a fantastic addition to processing 4D by masking and cutting at the source in Agisoft after each build.
Thanks, Lee
