Re: [PlayerStage-Gazebo] urgent!!! cameras not working

[Nate K. <nat...@gm...>]

Hello,

Could you trying running gazebo without the wxWindows interface? When
you try this, could you add this flag "<saveFrames>true</saveFrames>"
to the ObserverCam. This will write a series of images to disk when
you run gazebo. Check to make sure the images seem correct.
