Hi @arunava_nag, thanks for the report.
I couldn’t reproduce the original Qt issue but could reproduce the ROS1 error.
You’re totally right, The wiki has been updated to reflect the new executable location.
I could reproduce this indeed. Though these meshes are not necessary to visualize the robot and by setting the Fixed Frame to “world” I could display the robot model with all the links and associated meshes.
At some point I had some missing transforms as well. It looks like only the /tf_static topic had data but I didnt receive anything on /tf (on the ROS2 side so nothing was bridged on the ROS 1 side). Killing and restarting the dummy_robot_bringup.py launch file fixed it.
In RViz2 it worked out of the box by simply running the dummy_robot_bringup launchfile in a terminal and RViz2 in a second terminal.
Hope this helps,
