ValueError: no field of name f_dc_0

Hi all,

I tried to using this addon in multiple versions of Blender, from 3.6LTS to 4.0 4.1 and 4.2

I always face the same error:

Python: Traceback (most recent call last):
  File "C:\Users\render\AppData\Roaming\Blender Foundation\Blender\4.2\extensions\user_default\gaussian_splatting_io\__init__.py", line 74, in execute
    features_dc[:, 0, 0] = np.asarray(plydata.elements[0]["f_dc_0"])
                                      ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^

    return self.data[key]

    res = super().__getitem__(index)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: no field of name f_dc_0

I see others are facing the same issue but I have not found a proper solution for this. I am using the latest version from this repo. Anything that I can do?

Hi,

I faced the same issue on different versions as well,
It stopped giving me the error when I imported a .splat instead of a .ply. I hope this will help!

I was getting the same error with this add-on as well with the Kiri Engine one.
If you are using Polycam download the SPLAT .ply, instead of the regular one.
