Hi everybody, I'm kind of new to ROS and I am working with a TIAGo robot for my master thesis project, hence I am following the tutorials from ROS.org to get started.

The problem is that I cannot properly visualize marker when following the Octomap tutorial. The Gazebo simulation and Rviz are properly connected since I can see tiny points where the objects are supposed to be, but no colored cubes. What could be the reason for such a behavior?

I followed tutorial from ROS.org also for the installation of ROS and TIAGo packages. I am working with ROS Melodic and Ubuntu 18.04.

Thanks to whoever is going to help me!

Hello,

Thank you for your message, would you have a screenshot of what is happening?

Are you using your computer or the provided docker? Maybe you could try within the docker to be sure that no other packages interfere with it:

Maybe it is only a visualization issue in rviz, could you try to change the resolution of the rviz window?

Best regards, PAL Support

Thank you for your answer. I have not been using MoveIt in Gazebo for a while. I cannot remember if I solved the problem when running the tutorial in simulation, but I am sure I could run it properly against the real robot. This makes me think that everything is ok in Rviz, as in both cases I was using the same Rviz configuration file.

As for your question, I was using my computer. If I have some time, I will try to reproduce the issue and report about it.
