Starting with C-Turtle, gazebo will no longer require environment variables: LD_LIBRARY_PATH, GAZEBO_MEDIA_PATH and OGRE_RESOURCE_PATH. We are switching to using pluginlib to setup the corresponding resource variables.

Ogre Resource Path

From C-Turtle and on, the gazebo binary automatically looks for ogre package path, so nothing needs to be specified by the user.

Gazebo Media Path

Gazebo automatically looks in subdirectory Media/* for resource files, e.g.:

As of C-Turtle release, any package that exports gazebo_media_path to gazebo, and has direct dependency on gazebo, i.e. manifest.xml contains these lines

 <depend package="gazebo"/>
 <export>
   <gazebo gazebo_media_path="${prefix}" />
 </export>

Then, the package's subdirectories Media/* will be automatically searched for gazebo materials, textures and meshes.
