Nerfacto producing very bumpy meshes

[desifisker]

So I have been working with Nerfstudio for a little bit, and needed to update it a month or so ago from an older version, circa October 2024, to make sure I had a bug fix to allow for colmap coordinate frame consistency, so I could create a scaled mesh that is accurate to the real world.

Prior to this update, I was able to produce nice smooth meshes like this:

After updating NerfStudio and my colmap version, I was able to start producing scaled meshes, but they have been very bumpy like this: (same imagery, but instead of using ns-process, I use colmap directly, geo-reference the reconstruction to scale it, then scale it down by a factor of 100 so its not too big for nerfacto)

I thought maybe it was the version of colmap that was creating this issue, but now I think it comes from using the following command to train the nerf, which involves going from the 3 .bin files from the colmap reconstruction instead of using the .json that comes from ns-process:

ns-train nerfacto --vis viewer --data data/nerfstudio/DomeOrbit2Apr27Redo --viewer.quit-on-train-completion False colmap --colmap_path Scaled_1_100 --downscale_factor=1 --orientation_method=none --center_method=none --assume_colmap_world_coordinate_convention=False

Has anyone experienced this or may know if/what I'm doing wrong?
