how to change the default model website to look in, ros indigo
Whenever I try to open the willowgarage.world file, it starts looking for namespaces "Warning [gazebo.cc:215] Waited 1seconds for namespaces". Then it gives an error saying "no namespace found". I think it starts looking for the same world file or it's model in website "http://gazebosim.org/models", it might be possible that the site doesn't reply anything so i want to change the website to "models.gazebosim.org" because it's working. So I want some help to change the same, on how to change the website that it looks into. Further, I wanted to know how could I install all the models from this site on my computer so that it could find these models locally and that it doesn't need any internet connection to be able to do so, I really need help people.
