When making an example python scene for my BlenderMaterial Controller, I had a to use a reference to another Node. As I used a reference to my node "@/LiverImport/Liver/Visu/VisualModel" I got a Segfault when opening the script using the command runSofa scn_py.py.
I can get through this by removing the "@" in target_path.
Here is the undocumented version of my controller :
class BlenderMaterial(Sofa.Core.Controller):
def __init__(self, *args, **kwargs):
Sofa.Core.Controller.__init__(self, *args, **kwargs)
self.addData(
name="blend_file",
type="string",
value=kwargs.get("blend_file", ""),
help="Path to the .blend file"
)
self.addData(
name="material_name",
type="string",
value=kwargs.get("material_name", ""),
help="Name of the material"
)
self.addData(
name="target_path",
type="string",
value=kwargs.get("target_path", ""),
help="Path of the target model"
)And the part where it crashes :
material_component = BlenderMaterial(
name="plastic",
path="@/Liver/BlenderMaterial",
blend_file="library.blend",
material_name="plastic_01",
target_path="@/LiverImport/Liver/Visu/VisualModel"
)Here is a link to a Gist with more documentation and the whole script file to reproduce the error.
I tried using a debugger to see where exactly it crashes, with no surprise it's when the constructor is called. I get this crash consistently on Linux (Ubuntu Budgie 24.04) and Windows 11 Enterperise IoT.
