farrer of OpenGameArt submitted a patch , which allows loading of .obj models in Trigger Rally.
Not having this functionality makes it harder for artists to create UV textures for the game, which is something we desire to be easy, so that we can replace the current license-unknown car textures with good-looking freely licensed ones.
Quoting Scribe from a thread  on OpenGameArt:
"and thats great if you can now use .obj files as I think it will mean more users will be able to help you more easily."
Can someone with coding skills please review the patch?
