Hi,  
I am working on a big project with more than 12000 photos. The area covers 110 km2 in a mountainous area.

 ![image](https://global.discourse-cdn.com/pix4d/original/2X/2/262a0494acd90def7d20decc8fa7e1d84818cc18.jpeg)  
It was realized in 3 parts which have been merged. For sharing 3dmesh on sketchfab, it is necessary to degrade the resolution of the whole model.  
Question: Is it possible to extract a limited sector from the entire model and treat it separately for better resolution?

Hi @pix4d.geops,

I would use a processing area. Nice project by the way.

Hope this will help,
