How to generate occupancy grid (not from a png file)

Hello there!
Is it possible to generate the occupancy grid map from the /map ROS Topic [ nav_msgs/OccupancyGrid]?
There are no outgoing/incoming messages from the codelet !
I would appreciate any help. Thanks!

On the Isaac side:
OccupancyGridMapLayer reads map from png file. Please see “filename” parameter in the documentation.
Other codelets, GridSearchLocalizer for example, read it using the “map” parameter.

Does that answer your question?

Just saw your title, which indicates you do not want png file. This is not supported at the moment, but you can write a codelet for it.
