Hey zhengwang,
Thanks for the reply. Unfortunately, I can’t use Isaac Sim 5.0.0 due to my company’s regulations.
This problem is baffling; I have several of the exact same action graphs publishing different objects. Most of them are working correctly, but some are broken like this, and I haven’t been able to fix them.
However, I managed to find a solution by publishing the values using standard std_msgs. It’s a detour, but it works effectively.
