What is an IRR file?

An IRR file is a 3D file created by Irrlicht, an open-source 3D engine written in C++. It contains a scene graph, which includes particle systems, animators, and materials in XML format that Irrlicht references to create game scenes. Each IRR file may include user data, such as links to .IRRMESH mesh files, for scene nodes contained in the file.

More Information

An example call to load a scene, or IRR file, in Irrlicht is below:

// load the scene
if (argc>1)
       smgr→loadScene("example directory/sample.irr");
