I upped the gap fill steps. it did make some areas that were ‘missing’ have something but the lines are still all melted. Curious what other options I could try to get straight lines? I have used webODM on similar flights and don’t know why this one is so bad.
Similar problem: in Pix4D all orthophoto looks great, the WebODM has a wavy image.
The shooting was conducted on DJI Phantom 4 Adv

What settings should be in order to obtain acceptable orthophoto?
I read this topic and tried with the following settings:
Options: texturing-nadir-weight: 32, mesh-size: 500000, dsm: true
The result was better, but still the objects are slightly wavy and the buildings have some side walls.
I also noticed that the file generated in Pix4D has a size 300 Mb against 90 Mb in WebODM
How else can you improve the quality of the orthophoto? Processing 85 photos takes 1 hour, I am ready to spend more time, since I do not do commercial activities, but the quality of orthophoto is important to me.
Overall, ODM is an incredibly cool system!
I tried to increase some parameters, orthophoto as a whole became quite good, but the roofs still look very wavy.
