Campus Unbound scene extracts triangular mesh incorrectly

[whx-code]

Hi, I entered a campus scene taken by a drone and the rendered image is correct, but the extracted triangle mesh is wrong. Here are the commands I am executing：
python render.py -m <path to pre-trained model> -s <path to COLMAP dataset> --mesh_res 1024 --unbounded
Did I execute the wrong command or do I need to further optimize the mesh extraction algorithm?

The auto mesh estimates the bounding box and center using the cameras. You should check if you cameras can provide accurate estimation.
