Gazebo system plugin tutorial problem: no frames saved

I am doing gazebo system plug in tutorial ( link )

After running the plugin, I suppose to have several pictures saved in /tmp/gazebo_frames directory. However, when I checked, I didn't even have such directory, let alone the frames.

Anyone has the same problem with me? What is the solution?

Side question: I know that gzserver is to run the gazebo server, but what does the & modifier do in gzserver & command?

what gazebo version are you using? I tested with gazebo7 and it seems to work fine.

The & puts gzserver process in the background, freeing the terminal to run another proces, i.e. gzclient

@iche033 I'm using gazebo 7 on Ubuntu 16, ROS Kinetic. You found the frames in /tmp/gazebo_frames folder?

yes I see the images in /tmp/gazebo_frames. When running the gzclient command with -g to load the plugin, add --verbose and see if that prints out any error messages

had the same issue... Just forgot the export part, that wasn't in this part of the tutorial :

export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:~/gazebo_plugin_tutorial/build/

that solved the problem for me . . .
