ABSTRACT
Game engines are software built to make games. They have already built frameworks or modules for rendering Inputs, physics, artificial intelligence, Networking, UI, VFX, and Audio. Game engines usually have an editor to build level and other content. They often support a set of programming languages for programmers to create game logic. This chapter discusses the basics of Unreal Engine which is among one of the first and best game engines. When an asset is imported to Unreal Engine, they are categorized into different types. The narrow color bar at the bottom of each asset shows their type. The assets with cyan color are static meshes. There are many settings under the lighting Mode in the Translucency section of the material. When lights hit the surface of a different medium, the direction of the light got changed (refracted).
