Hello -

I have an valid pix4d mapper educational license. The mosaic editor is not working to export the new ortho mosaics after cropping. I can open the original ortho mosaics that were generated, crop it with the draw tool, save and export. But when I open the exported file, it is just like the original ortho mosaic. Can you help me on that, please?

@amartinsalmeidaber2 can you describe what you mean by “cropping”? PIX4Dmapper’s mosaic editor can be used to change the texture of the orthomosaic, to generally remove artifacts left by moving objects during the image capture or distorted edges due to lack of overlap.  
If you need cleaner orthomosaic edges, I recommend you draw a processing area in the rayCloud, at least before running step 3 to generate the orthomosaic. If you draw the processing area before step 2, the processing area will be used for all your step 2 and step 3 outputs.
