How to add transparent visual materials in Isaac Sim?

I want to make some objects “half”-transparent in Isaac Sim.

I found some very cool visual materials here and tuned OmniPBR Opacity parameters. However, it seems that when opacity_constant is below some threshold, the object is completely invisible, even for some large opacity_constant values like 0.8.

Did I miss something? How to control opacity in Isaac Sim?
