Though the initial question about improving resolution was answered by @GordonSumerling  (thank you), @st_123 reached out to us through Technical Support channels and provided additional details. It was determined that the challenges that led to this question were caused by the data capture and affected all the outputs, not just the mesh.  I'll share our findings and the tips we provided here in case they can help others in the community:  Not all photos were captured the same day. All images in a mission should be captured on the same day, and ideally close in time to ensure that environmental conditions remain similar, particularly lighting. Photos show blur, and the data was not captured using Site Scan Flight. We recommend using Site Scan Flight to capture data when using a supported drone like the P4R used here because it optimizes flight speed and camera settings for mapping, which many other apps (including DJI's) do not. At the least, increase the shutter speed to ensure photos are sharp, ideally 1/640s or faster, with Shutter Priority enabled.  Overlap was excessive in certain areas, which can lead to long processing time and server timeouts on a larger datasets like this one. Using Site Scan Flight would also help here, some other apps are known to incorrectly calculate overlap. Flight elevation was inconsistent throughout the different data collection flights. Use Site Scan Flight with Terrain follow, this will ensure that flight height above ground remains constant, even if the pilot needs to reposition for different flights. Drone/camera hardware:  Ensure the lens is clean before each takeoff. Takeoff from a hard surface and ideally clean takeoff pad to avoid dust pickup during takeoff. In warm and humid environments, let the drone hardware acclimate to ambient temperature for about 5 minutes before taking off (avoid going from cold and dry air conditioning of a car/truck directly to outside). This can also help prevent condensation appear on the lens. GCPs: make sure to use targets that can be very precisely measured in the images, such as checkerboards. Painted "X"s or visible identifiable features like corners cannot be measured as precisely.  Some images were captured in cropped resolution, 4864x3648, rather that the full 5472x3648. Site Scan Flight would set this automatically to the maximum, but if using another app be sure to use full resolution for best results.   ... View more
