Hi @PARKBONG
I am not sure if the name of the node can be changed from OmniGraph…
but you can always modify the exts."omni.isaac.ros_bridge".nodeName extension setting (PATH_TO_ISAAC_SIM/exts/omni.isaac.ros_bridge/config/extension.toml) to change the name of the node before launching Isaac Sim
The recommended way in your case is to change the name from command line argument, example:
./isaac-sim.sh --/exts/omni.isaac.ros_bridge/nodeName="NewNodeName"
