About the path of the objects

[pengzhi1998]

Hi everyone, I'm trying to build my own underwater environment. Thus, I'd like to import some of the built objects. However, in cirs.xml, the objects are imported in already. Even though when I rosrun the uwsim, I'm able to see the objects (such as the blackbox), however, I cannot find the OSG files for the objects (blackbox_uib_trimesh.osg for example).

And when I go to the directory of data, I can only find "scenes" as well as "shaders" but there is no "objects" and other useful directories. Is there anyone facing similar problems? Thank you for your help!
