Hi everyone,

Rviz doesn't display the produced map of octomap_server_node properly. I only see gray dots in place of those fancy colored cubes (grids). I'm using the official octomap_server package installed on ROS Melodic. I've created this setup today with a fresh ROS Melodic installation. It's working properly with an older ROS Melodic installation on another PC.

Does anyone have an idea of what's going on here?

Are you German? Or configured a locale with , (ie: comma) instead of . (dots) for decimal separators?

What is the output of echo $LC_NUMERIC?

I'm Turkish. In Turkey the , is used as decimal seperator. The output of echo $LC_NUMERIC is tr_TR.UTF-8.

You can compare this with the other machine where things do work, but to test it on your machine, set LC_NUMERIC to en_US.UTF-8 and see whether things improve. Note it would only be active in the shell you write that in, so don't expect it to be permanent.

If that makes things work normally, you're running into #q272692 and similar issues.

I've changed it in etc/default/locale to US version and relogged but still it shows the same gray points only. I'll check the older system later.

Just remembered that it could also be a missing nvidia driver. See #q337916.

Yeah it works. I'm using an GTX 1070. In the Software & Updates GUI of Ubuntu I changed my driver under the Additional Drivers tab from xserver-xorg-video-nouveau (open source) to nvidia-driver-435 (proprietary, tested) and rebooted. Thanks for the help. I can select your answer as the best if you'd like me to do.

I think I'll actually close this one, as it's essentially a duplicate #q337916.

Remember to put back your LC_NUMERIC setting.
