Hello,

I got this error while executing roslaunch active_3d_planning_app_reconstruction example.launch following steps in your readme

...
Traceback (most recent call last):
  File "~/catkin_ws/src/mav_active_3d_planning/active_3d_planning_app_reconstruction/src/experiments/gps_odometry_simulator.py", line 11, in <module>
    from mav_active_3d_planning.msg import OdometryOffset
ImportError: No module named mav_active_3d_planning.msg

Packages are successfully built on Ubuntu 18.04, ROS melodic. And I have checked the connection to unreal_cv_ros game: INFO:__init__:211:Got connection confirm: 'connected to RealisticRendering'

The planner starts running afterwards but got this error

I'm not sure if these errors are related.

Thank you for pointing out this error (which was due to renaming), it has been fixed as of #20 .

The second error is due to the fact that the RealisticRendering demo provided by UnrealCV does not contain the augmented Plugin. You can either run RealisticRendering in standard mode or run a world with the full Plugin (e.g. CityBuilding) in fast mode.

Great! Now it works.
