I am publishing an octomap from a .bt file with octomap_server such that:

$ rosrun octomap_server octomap_server_node btFile.bt

But when I try to visualize the octomap in RViz, I am only getting this ¿occupancy base? (see image).

As you see, it is clear that the transform from /map to blocks is not published. Does this need to be there to be able to visualize it? Also, it is saying that the frame blocks does not exist.

In OCTOVIS, I do not have this problem and the whole octomap is loaded successfully (see image below).

How can I solve this?

I solved it.

Surprisingly, when I added the OccupancyMap by doing Add->By topic, it worked and the octomap appeared instantly. I am not sure if this was a refreshing-related problem. If I tried to add it in another way, the octomap was not shown.
