I am processing an orthophoto of ongoing construction, the building itself seems to come out OK but the utilities on the roof are heavily distorted. Any suggestions on how to fix this? I did not resize the images and used the preset “High Quality”

Try to increase the `--mesh-octree-depth` value to `10`. Beside that, we’re working to improve the outputs of urban areas. Check [Repost: Upcoming improvements to OpenDroneMap - Better everything. - OpenDroneMap](https://www.opendronemap.org/2018/07/repost-upcoming-improvements-to-opendronemap-better-everything/) for a preview of what’s coming soon (hopefully within the next month).

Thank you for the reply, I am very excited for the upcoming updates.

I increased the Mesh-octree-depth to 12 first, I will try 10 now. What front/side overlap do you suggest? I can spend more time flying if it means better orthomosaic outputs.

83% overlap and side lap.
