The ortho has problems with the edges too:
Ortho and 3d model above buildings poor edges
I have been trying repeatedly to create a good model of a new housing development.
There is a lot of detail on the roofs, and its not coming out well, despite having 12+ overlap. In this last attempt, I flew a Map Pilot Pro auto route at 60m altitude, then did a manual run of obliques around the buildings. This is with a Phantom 4 Advanced.

For context, here is a more complete view of what Im trying to model:
Turn off the Full 3D setting until you can get a decent model without it. You really need to give the system at least 25 looks at anything you want to turn out well for a good 3D model.
With all these reflective surfaces, you absolutely do not want to do this model at solar noon. The solar panes and the roof have huge differences between successive images due to the sun reflecting directly into the camera.
These topics here are directly affecting your outcome:
Great, thanks for the help @Zane
So, I should fly higher, turn off full3d, and get more photos by flying more overlap and perhaps a double grid. I am using a circular polarizing filter too btw. One thing I dont know how to deal with is the tradeoff between solar noon = no shadows and outside solar noon = shadows but sun hotspots. Can I still fly at solar noon if I use the polarizing filter? I have so far been prioritising avoiding shadows, but perhaps this is not that important.
Reflective surfaces near solar noon are going to be problematic even if you have a CP filter on. The hard reflections will be really hard to get rid of. Flip through your images and you will see.
You can try to address this is with more overlap but even that may not be enough. Full grid won't do much but how you plan the orientation of your passes can help reduce the reflections.
Rerunning the data you already have without the Full 3D setting will likely give you a better result.
For the sake of others, I think the reflection on the solar panel at the middle bottom of this photo is an example of the effect that must be messing up the processing
