An Example of a YAML Scene File

An example of a simple but complete scene is given below. The scene contains just a camera and a cube object. Note that the file must start with the two lines

%YAML 1.1
%TAG !u! tag:unity3d.com,2011:

…in order to be accepted by Unity. Otherwise, the import process is designed to be tolerant of omissions - default values will be supplied for missing property data as far as possible.
