The pySPlisHSPlasH does not display new properties

[happtain]

Hello,
I used addField in FluidModel to add some properties to the fluid and modified the ParticleExporter_Partio file so that these properties can be seen in the simulator and PartioViewer. It works well in the C++ version, but I can't see these properties when I run the simulator with pySPlisHSPlasH, and there are no such properties in the partio file output by pySPlisHSPlasH.
I didn't write new functions in FluidModel and ParticleExporter_Partio. What should I do to make my pySPlisHSPlasH also display and output new particle properties?

Best Regards
