How to make a mesh transparent using the pythin I isaacSim

[vahidashkani]

Hi, I have a volumetric (tetrahedral) mesh in Isaac Sim that contains several objects inside it. I would like to make the outer mesh transparent so that the internal objects remain visible during the simulation.

I’m looking for a Python-based solution in Isaac Sim (USD / Isaac API), preferably by modifying materials or render properties programmatically. I’ve searched through the documentation and examples but haven’t been able to find a clear or working approach.
Could someone please explain how to make a mesh transparent in Isaac Sim using Python, or point to a relevant example?

Thank you!
