Description

The Attribute class is the base class for all material attributes. A list of material attributes is supplied to the RenderSegment class by either attaching a material with the RenderSegment::SetMaterialObjectPointer function or by setting an auxiliary attribute list using the RenderSegment::SetMaterialAttributeList function. These material attributes describe to the Graphics Manager how a renderable object should be shaded.

A Geometry node can have a MaterialObject object attached to it that holds a list of material attributes. In this case, the list of material attributes is automatically applied to the Renderable base class of the Geometry node when it is preprocessed.

Base Classes

`ListElement<Attribute>`	Attributes are stored in a list by the `MaterialObject` class. The `Renderable` class also uses lists of attributes.
`Packable`	Attributes can be packed for storage in resources.
