Hello,
I am using Isaac Sim 6.0.0-rc.22 on Ubuntu 24.04.
I launched the Nova Carter Robotics Example and the robot appears corrupted after loading.
Observed behavior:
The robot is rendered completely white.
Some components that appear to be camera or sensor related are rendered at completely different locations from the robot body.
These components appear to be floating in space and overlapping the robot scene incorrectly.
The issue occurs immediately after loading the Robotics Example.
I have attached two screenshots showing the issue:
Nova Carter rendered completely white.
Components appearing at unexpected locations relative to the robot body.
I also attached the complete console output generated while reproducing the issue.
What I have already tried:
Deleted ~/.cache/ov
Deleted ~/.cache/omniverse
Deleted ~/.nvidia-omniverse
Restarted Isaac Sim
Re-synchronized extension registries
The issue still persists.
Environment:
Isaac Sim 6.0.0-rc.22
Ubuntu 24.04
NVIDIA RTX 4070 Ti
ROS 2 Humble
Has anyone seen this issue before, or is there any known problem with the Nova Carter Robotics Example in Isaac Sim 6.0 RC?
Thank you.
The complete console log is attached below.
