Topic Description

Detailed Description

I have set up my own stage in Isaac Sim, which I then link to the Agend SDG as my “scene asset path”. I use the “Set Up simulation” button to include the amount of characters and cameras I want in the scene. Then, when I start the simulation Isaac crashes and shuts down, giving me the crash dump logs I have below.

Steps to Reproduce

  1. Use a custom scene for the “Scene Asset Path” in Agent SDG.
  2. “Set Up Simulation” based on the numbers you need.
  3. Start the simulation.
