Games often have a lot of resources, such as grids, materials, textures, animations, shader programs and music, game engine as a tool to do the game, naturally to provide good resource management, so that the game developers in the simplest way to use resources. Game Engine resource management consists of two major parts: offline resource management and runtime resource management. In this paper, the former is briefly introduced and combined with Unity3d and ogre for analysis. Resource Authoring
