Navigation local costmap not showing up

[MrOCW]

Hi everyone, I have a pre built 2D map and I'd like to use it for autonomous navigation on a custom robot that I built with an Arduino Nano and Jetson Xavier NX. However, I am not able to get the local costmap running although the global costmap works fine.

However, changing costmap to map does display the local square map, though it is empty

You are drawing behind with an alpha of 0.7. Try making the alpha 1, and deselect the draw behind button ?

@DatSpace I've tried with many different values before, draw behind selected and unselected, did not make any difference unfortunately.

Have you verified that the topic actually receives the data ? With rostopic echo <topic_name>

I mean it might be a visualization problem, or a settings problem, from the cost map side.
