How to add ROS topic to the Intel Realsense plugin ?

Hi everyone, I am trying to get the topics that are published by my [simulated Realsense camera](https://github.com/intel/gazebo-realsense) back to ROS, but I haven't been successful yet. I tried by following [this tutorial](http://gazebosim.org/tutorials?tut=ros_gzplugins) , but it didn't seem to work, I didn't get any related topic in rostopic. How you will do that ? My current work state : rrbot/camera1image_rawcamera_infocamera_link [...] I am using Gazebo 8 with ROS kinetic in a Ubuntu 16 virtual machine. Cheers
