Project – Think of a project as a folder holding your game. Unreal 4 comes with several styles of projects:  First Person, a Third Person, Vehicle, Empty…

Level/Map – Levels (often referred to as maps) are the individual scenes in your project. You might have many scenes in your project.

Actor – An actor is any object that can be placed into a level – Cameras, Lights, Materials, Static Meshes (objects made in a 3D modeling program – chairs, trees,, rocks etc), Geometry and Characters are all actors.

  • Geometry – Unreal uses a simple system of walls, floors, and staircases that allow the designer to quickly flesh out a level. Geometry can be cut to make doorways and windows .

  • Static Meshes – For more complex shapes (people, trees, rocks etc) you need to use static meshes. Unreal comes with library of static meshes. In addition there are “collections” and “packs” of meshes on the “I” drive of the SoCal ROC computer system. You can import these into your level.
    Lastly, you can model you own original static meshes using 3D Max.

  • Materials – A material is collection of textures that give your geometry and static meshes their look.

  • Textures – A texture is a sub-part of a material. A texture can be a photo of brick wall, color, an amount of glossiness, and even a special texture called a “Normal” that creates a 3D illusion of roughness.

Components- A component is a piece of functionality that can be added to an Actor. Components cannot exist by themselves, however when added to an Actor, the Actor will have access to and can use functionality provided by the Component.

Blueprint - A Blueprint is the visual scripting system inside Unreal Engine4 and is a fast way to start prototyping your game.
