Mesh not being seen by RViz

edit

Hi everyone,

I'm trying to import a simple car wheel 'dae' file although when I launch it, nothing appears on RViz, and in my terminal I get the FileNotFoundException error. I'm following this convention "package://packagename/path," which I found from http://wiki.ros.org/urdf/XML/link. Not sure what file path I should put down for it to find it.

I get the following error when I run this:

Any suggestions would be much appreciated!
