Detailed Description
Hello,
I’m using a python script for dynamic compostion of an Isaac Sim scene from separate USD files, according to input arguments (specifically unitree_sim_isaaclab/sim_main.py at main · unitreerobotics/unitree_sim_isaaclab · GitHub ). I’d like to add support for ROS2 camera, for which I created a USD file with an Omni Graph (following the tutorial ROS 2 Cameras — Isaac Sim Documentation ). However, the problem is with setting inputs:cameraPrim attribute, as it is of type custom rel, which is probably the reason why it is not listed among other attributes (`prim_node.GetAttributes()`) and thus cannot be adjusted via prim_node.GetAttribute("inputs:cameraPrim").Set(...).
Is there a way to programmatically access/adjust external relationships of OmniGraph nodes? I searched the documentation, but could not find a clue about this particular process.
Thank you for your help
