Hi,
Thank you for amazing work.
I have used instant-ngp, nerfstudio to generate mesh. However, sdfstudio impress me by mesh generation.
When I use sample data, I always get good render and mesh.
However, when I use custom data, results were always poor although I have done experiments and follow all discussions in this page.

Could you give me advice to process with this data: https://drive.google.com/file/d/1hLnwXon29bc4SiyuxiV32VAfQnZY2gTd/view?usp=share_link
As screen shot of above shared data like this:

The steps I have done as followings:

• Used colmap to generate transforms.json file as usual in instant-ngp
• Tested with instant-ngp, give a very good result (video 1 below)
• Tested with nerfstudio by:
  ns-train neus-facto --pipeline.model.sdf-field.inside-outside False --vis viewer instant-ngp-data --data D:\Hung\sdfstudio\data_cu\elephantNERFSDF\PNG_colmap
  Give a not good render
• I also use scripts ns-process-data, then render with nerfstudio, give a good result
• used script process_nerfstudio_to_sdfstudio.py to convert from nerfstudio json file to meta_data.json file, and run with sdfstudio (neus-facto), got a very poor result (video 2).

I have checked very careful discussion in #2 (#2), and #49 (#49), but rendering result is very poor like #49.

Below videos are rendering with instant-ngp

And rendering with sdfstudio

The mesh I got from sdfstudio like this:

Highly appreciate with any help.
