I have checked stl file list, Is this okay?

Do you see the robot in Isaac Gym environment? (without --headless)

[jingxiangmo]

What do you see just running python sim/train.py --task=stompymicro --num_envs=4096?

Thank you for your reply. I can see the robot with or without the -- headless parameter, but it is an incomplete and missing component robot. I guess I am missing the STL file and I don't know how to download the complete robot STL file. I used OpenLCH/sim/sim/scripts/download.assets.sh to download the file. If I run task stompymini with “python sim/train.py --task=stompymini --num_envs=4096 --headless”, I think the result is normal and there are no errors. I have trained 5001 iterations and play.py can walk normally
