I created a simple .world file:

<?xml version="1.0"?>
<sdf version="1.4">
    <world name="office">


My launch file also adds a robot to this world. It launches fine in gazebo, I can see the gray ground plane with grid markings on it and also my robot. image description

Next I created a simple building layout (some walls created using Gazebo's building editor). I saved the building model and added these lines to my .world file:

    <pose>25 20.2 0 0 0 0</pose>

When I launch the file again, this time it takes ages to launch. I see a 'Preparing your world ...' screen for a long time (~10 mins): image description

and then I see this dark screen:

Other solutions which I have tried and did not work for me are:

  1. Adding the following code to the package's package.xml

       <gazebo_ros gazebo_model_path="${prefix}/models"/>
       <gazebo_ros gazebo_media_path="${prefix}/models"/>
  2. Adding the environment variable GAZEBO_MODEL_PATHto my .bashrc file:

    export GAZEBO_MODEL_PATH=/home/my_user/my_catkin_ws/src/

There are no errors thrown in the terminal. What am I doing wrong?

I placed the model files in the ~/.gazebo/models directory and changed the code in the .world file to:

    <pose>25 20.2 0 0 0 0</pose>

Its working fine now. However I still don't know how to provide a reference to models which are not in the ~/.gazeo/models directory.

What is the output of "echo $GAZEBO_MODEL_PATH"?
