Based on my teaching experience in the Art colleges, I found potential usages of a game engine as a tool for fine art. This paper will provide new way to use game engine; Making a Virtual Art Gallery with a real-time 3D rendering game engine and Making a Draft movie for a 3D Animation in postproduction using a real-time 3D rendering game engine. This paper will also provide the case study of various projects draft movie for a 3D animation with Real-time 3D Rendering Game Engine. This study will provide new possibility of game engine.
