rviz 3D

[user+90]

When I say download map, I get such an error. I cannot get a 3D image on rviz. Actually what I'm trying to get is to draw a path when I give a 2d goal target, but I can't. I don't think it's because it doesn't come in 3D.

The namespace of the rtabmap node may be wrong in the MapCloud config. For example, if I have:

rosnode list
/rosout
/rviz_1674953592101951521
/zed/rtabmap
/zed/rtabmapviz
/zed/rviz
/zed/zed_node
/zed/zed_state_publisher

I should set the namespace parameter in MapCloud display to "zed" like here:
