Hi @atbecker ,

Try to run this line before starting/launching Rviz2:

cd ~
source ~/simulation_ws/install/setup.bash

Let me know if this solves your problem.

Girish

EDIT (27/02/2023): I think what @rzegers said should be correct. What I suggested would most likely not work.

Hello @atbecker,

in addition to what @girishkumar.kannan suggested, please try this command here:

source /home/simulations/ros2_sims_ws/install/setup.bash

just before you run ros2 run tf2_ros tf2_monitor camera_bot_base_link rgb_camera_link_frame.

The ros2_sims_ws workspace is where those .dae meshes are located and it seems that it can’t find them.

Please let us know how it went.

Regards,

Roberto
