Loading Python file in SofaUnity

[BinhTran17]

Hi, I have a simulation in SOFA framework, and I want to put it in Unity. I have 2 files, one .scn and one .py, and 2 corresponding .msh files, all put in this GDrive folder. The files work well in SOFA 24.12.00 but I can't get the Python one to work in Unity.

• I have tried a couple of combinations of Unity versions (2022.3 and 6.2) and SofaUnity versions (24.12, 25.06, and from Unity Assets store)
• The Assets store version uses 24.12.00 DLLs.
• My laptop is running Windows 11.
• Python and required packages versions: Python 3.12.1, numpy 2.3.5, scipy 1.16.3, and pybind11 2.12.0.
• I tested on 4 demo scenes: Demo_01_LiverInteraction and Demo_02_LiverInteraction-HD from Interaction folder, and LiverPyhon and LiverPyhonController from Python folder

Following are my findings

Unity Version	24.12.00	25.06.00	Assets store (24.12.00)
2022.3.62f2	Cannot load .py files, only shows DefaultVisualManagerLoop and DefaultAnimationLoop when load. Demo_01 and Demo_02 of interaction don't have lighting. Python demo scenes don't move or interact. [Ref A]	Python demo scenes show nothing by default, SofaContext only include DefaultVisualManagerLoop, DefaultAnimationLoop, and SofaCollisionPipeline. Loading .py files yield same problem as SOFA 24.12.00. [Ref B]	Similar to SOFA 24.12.00, but a texture loading error makes everything pink. Cannot see the animation. [Ref C]
6000.2.6f2	Cannot load either .scn or .py files, the Scene Filename field doesn't change.	Same as above	Same as above
