Ros2bag+nvblox running issues

[rodineye]

Isaac Sim Version : 4.2.0
Operating System : Ubuntu 22.04
GPU: NVIDIA GeForce RTX 4070
Driver Version: 555.58.02
CUDA Version: 12.5

I initially followed the tutorial isaac_ros_nvblox — isaac_ros_docs documentation to run, the final command is

ros2 launch nvblox_examples_bringup isaac_sim_example.launch.py \
rosbag:=${ISAAC_ROS_WS}/isaac_ros_assets/isaac_ros_nvblox/quickstart \
navigation:=False

The running effect is ok, as shown in the following figure

Then I tried the following method
Run the command within a terminal

ros2 launch nvblox_examples_bringup isaac_sim_example.launch.py \
navigation:=False

Run the command in another new terminal

ros2 bag play ${ISAAC_ROS_WS}/isaac_ros_assets/isaac_ros_nvblox/quickstart

Nvblox did not report any errors, but it also had no result, as shown in the following figure

I have read the code of isaac_sim_example.launch.py and cannot see any special settings for ros2bag, so where is the problem? Can anyone help me? Thank you very much

Hey @rodineye! Thanks for pointing this out. I am able to replicate your issue. I have passed this to our internal team.

hey @zhengwang , I have solved this problem by setting the parameter (‘use_sim_time’, False) in nvblox_examples/nvblox_examples_bringup/launch/isaac_sim_example.launch.py, hoping it will be helpful to you
