Looks like you don't have write permission to add-on folder, where add-on is trying to create vtklog.txt. Are you running Blender as normal user?

Hi, please go through the tutorial examples in https://bvtknodes.readthedocs.io/en/latest/ug_nodes.html using the cubeflow example data to get familiar with data processing with unstructured grids. If Info node shows data like in...

Maybe this is ownership or writability issue. Please check file ownership and make writable file `~/.config/blender/2.83/scripts/addons/BVtkNodes-master/vtklog.txt` and `BVtkNodes-master` directory. If they have correct rights, you can edit and save `vtklog.txt`...

Hi, I can see your data in Paraview, but I'm not sure why XMLMultiBlockDataReader does not show any field data being read in the Info node. [See node example here...

I digged a bit deeper. Your data is multiblock data composed of 3D vtkImageData. So, the key here is to somehow merge blocks, and then to find VTK routines to...
