How does rviz use color? When I've spawned objects in simulation, they don't show up in the main rviz window, although I can see them in a camera window. Is there some way to make spawned objects (or even world objects) show up in the main rviz window? It is possible that I'm not seeing them due to an artifact of my setup -- I run most often in a VMWare box on my MacBook, and I have noticed a few peculiarities in this setup, but it kinda works most of the time. --wpd
