question about prim_paths #22

Hi, Thanks for the great jobs on Omniverse Isaac Gym. I have a question when I transfer policy from isaac gym. I used my own asset so I get a urdf file. I use isaac sim to import it as a usd file, but there is no prim_paths on isaac sim to save. So when I want to train by omni isaac gym, it shows wrong. How can I get prim file?

Hi there, when you import an URDF file as an USD file, you can save the imported USD stage as a .usd file. To retrieve the prim path of a particular prim in the stage, you can open the .usd file in Isaac Sim and use the Stage tab on the top right of the viewer. Pick the prim you'd like to get the path of, right click on the prim, and there will be an option to copy the prim path for that prim.
