Unable to open a custom map

Hi @sikang, thanks for providing this wonderful project. By following your instructions in the map making sections, I could record the voxel_map
topic through the launch file. However, when I tried to implement my custom model in ellipsoid_planner_node, the custom map didn't show up by showing the following error message.
[ WARN] [1657181193.172610214]: Fail to find '/cloud' in '/root/catkin_ws/src/mpl_ros/mpl_test_node/maps/building/aa.bag', make sure md5sum are equivalent.
[test_primitive-1] process has died [pid 4277, exit code -11, cmd /root/catkin_ws/devel/lib/mpl_test_node/ellipsoid_planner_node ~pose:=/move_base_simple/goal __name:=test_primitive __log:=/root/.ros/log/8e369782-fdcb-11ec-9e19-88366cf6d71f/test_primitive-1.log].
log file: /root/.ros/log/8e369782-fdcb-11ec-9e19-88366cf6d71f/test_primitive-1*.log
I thought it was caused by the topic cloud
is not recorded because rosbag record /voxel_map
only records /voxel_map
topic. I assumed that rviz shows map only through pointcloud data not voxel map. I have tried with many times and knew that if the bag file doesn't contain cloud
topic, then the above error message will come out. So, I recorded all the topics through the command rosbag record -a
and it removes the issue.
I want to implement your algorithm in custom built environments (gazebo world). Are there any easier way to get custom map in .stl format in Gazebo? If is not, is there any way I could open my custom map with voxel map
topic?
Many thanks.
