Detailed Description
A randomly-placeable object.SGMaterial uses this class to keep track of the model(s) and parameters for a single instance of a randomly-placeable object. The object can have more than one variant model (i.e. slightly different shapes of trees), but they are considered equivalent and interchangeable.
