I am currently testing a manual system I have cute some experience doing photogrammetry specially with drones. now I want to scann a car part. but I am having really bad results with the edges of the 3d model. I use agisoft metashape for merging the images together. here some images of the result.

As you can see the edge defenition its really bad. I will attach here one Image as a example of the photographs I took.

I did some paiting for the car part since its really reflective. But I am not getting a good result. The day was really cloudy so lighting conditions were perfect. I am using a "rebel camera canon t6i" I also tried with my phone taking pictures but the result was even worse. any ideas why this is happening?
