Originally conceived as a quick-and-dirty tool to allow a few 3D models to be converted to OGRE as testing data, the Quake to OGRE Mesh Converter grew out to be a bit more useful and complex. It allows models from various id Tech engines (MD2, MD3 and MD5) to be converted to the OGRE Mesh format, including animations, with a large number of customization options.
