I am running artrackalvar individualMarkers and individualMarkersNoKinect. The first fails to find the mark while the second finds it and tracks it.Here are my launch files: I can not see why this should be any thoughts? I am running in simulation in gazebo. Also why does the marker position show past the mark?

<launch>
    <arg name="marker_size" default="30.48" />
    <arg name="max_new_marker_error" default="0.08" />
    <arg name="max_track_error" default="0.2" />

    <arg name="cam_image_topic" default="/depth/points" />
    <arg name="cam_info_topic" default="/camera_info" />        
    <arg name="output_frame" default="/rrbot/camera_frame" />

    <node name="ar_track_alvar" pkg="ar_track_alvar" type="individualMarkers" respawn="false" output="screen" args="$(arg marker_size) $(arg max_new_marker_error) $(arg max_track_error) $(arg cam_image_topic) $(arg cam_info_topic) $(arg output_frame)" />
</launch>
