Hello, I’m working on a mobile project. I would like to download a 3D model from Pix4D capture. But I’m working on mobile and I need to downgrade the size (the number of polygons) of this model 3D without using a computer. Is there any way to do it from my mobile ? Thanks ! ---

Hi @kevinr, You can’t decrease the size of the 3D model without changing the processing option or just from your phone. To change the resolution of the mesh, you have to change the setting before processing as shown in the figure below. ![image](https://global.discourse-cdn.com/pix4d/original/2X/8/8d8daf2b9ad2c1fd5dfadd4bfb2543cfb6c6e091.png) ---

@Hi @Kapil_Khanal, Thanks for the answer ! Do you know if it’s possible to use Pix4D mapper on a server with command lines ? Best regards,
