Resource
From Yage3D Wiki
The Resource Package acts as an internal file system for Yage. It handles loading of 3D models, textures, sounds, materials, shaders, and more. Each of these exist as a file/class in the resource package and often include more extended functionality such as image resizing, sound buffering, and shader compiling/linking. This package also includes the resource manager, which can cache loaded resources, return them by reference, and ensure that no resource is loaded twice.
