Rendering and Blender Scene Loading Issues - 'UnicodeDecodeError'

[Masoudvahid]

Hello,

First of all, I would like to express my appreciation for your amazing work on Gaussian Frosting. It’s an incredibly interesting plugin, and I’m excited to be using it! I am currently trying to recreate the results I previously trained using the SuGaR repository, but I’ve encountered two main issues:

1. When I press Render Image or Render Animation, nothing happens and I don't get any output. There are no error messages or logs indicating what went wrong.

2. I am saving my scene as a .blend file in the <SuGaR>/blender/packages directory. However, when I run:

python render_blender_scene.py -p <PATH_TO_PACKAGE>

I receive the following error:

Using original 3DGS rasterizer from Inria.
[INFO] Using device:  cuda:0
[INFO] Images will be saved in:  ./output/blender/renders/a2

Loading Blender package...
Traceback (most recent call last):
  File "/SuGaR/render_blender_scene.py", line 60, in <module>
    package = load_blender_package(args.package_path, device)
  File "/SuGaR/blender/sugar_utils.py", line 17, in load_blender_package
    package = json.load(open(package_path))
  File "/miniconda3/envs/sugar/lib/python3.9/json/__init__.py", line 293, in load
    return loads(fp.read(),
  File "/miniconda3/envs/sugar/lib/python3.9/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf0 in position 20: invalid continuation byte

I have updated my old SuGaR repository and environment, and I am using Blender 4.0.2.

Any help or guidance would be greatly appreciated!

Thank you for your hard work and support!
