Transitioned from the original Pix4d to PixMatic several months ago. I have run 30-40 projects in that time, and have had no issues. Was attempting to run a new project today, and kept getting a calibration error, and when looking further, it appears to be failing at Feature Extraction. Checking the error log, there is nothing specific about what is failing, or how I can correct. Anyone have any experience with this error? I included the project logs that I exported as a zip file in a reply
