Hi,

I was wondering if it was possible to change the color of an Interactive Markers during run time? I tried to change the color of the mesh embedded in the Interactive Markers but nothing occurs when I update the Server:

server.get()->applyChanges();

The architecture of my Interactive Markers is :

visualization_msgs::Marker robot_mesh;
visualization_msgs::InteractiveMarkerControl robot_control; //contain robot_mesh
visualization_msgs::InteractiveMarker robot_marker; //contain robot_control

Thanks

A solution that worked for me was to just clear all interactive markers and reinsert them all with the new colors. Surprisingly, this works even while a marker is being dragged in rviz

In python its as easy as changing the markers color attribute.

marker = server.get("marker_name")
marker.controls[0].markers[0].color.r = 150
marker.controls[0].markers[0].color.g = 0
marker.controls[0].markers[0].color.b = 0
server.applyChanges()

It does change but not as you drag the marker for me. I need to hit reset or toggle transparency box to make the update happen
