Convert scene to tetra mesh error in eval of blender2mesh

[kaiobbarros]

My name is Kaio, I'm a brazilian PhD candidate in the photobiophysics area. I'm trying to make more complex simulations than my previous with MCX, but after the instalation of BlenderPhotonics, I couldnt make the first step. When I try to convert the initial Blender cube to tetra mesh, i get the following error:

Python: Traceback (most recent call last):
File "C:\Users\Kaio BB\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\BlenderPhotonics-master\blender2mesh.py", line 203, in execute

raise Oct2PyError(msg)
oct2py.utils.Oct2PyError: Octave evaluation error:
error: blender2mesh: function called with too many outputs
error: called from:
blender2mesh at line -1, column -1

Aditionally, when I click the object properties, theres no optical properties like "g, ua, etc" in the custom properties. I should create then manually with the "New" option or the options should show automatically?
Can U help me in some way?

Thanks for all your contributions with optic simulations.

can you upgrade your iso2mesh to the github version and try again?

Firts of all, thanks for your lightspeed answer!

I updated to the last version found on your git an then reinstalled the BlenderPhotonics, but unfortunately the same error. I tried others versions of iso2mesh too, just for peace of mind, but nothing.
