Asset Artist

Asset Artist

An asset artist must have both 2D and 3D art skills and is responsible for creating assets that appear in the game world. These assets include characters, weapons, vehicles, props, user interface items, and any other necessary game assets. Some asset artists choose to specialize in a specific type of asset creation, such as characters or vehicles.
