Material provides a way to specify the rendering of an entity. Any aspect can define its own subtype of Material so that a Material can be used to describe a visual element; for example, the way sound should reflect off an element, the temperature of a surface, and so on.
In itself, a Material doesn't do anything. It's only when it references an Effect node that a Material becomes useful.
In practice, it often happens that a single Effect is being referenced by several Material components. This allows to only create the effect, techniques, passes and shaders once while allowing to specify the material by adding Parameter instances.
A Parameter defined on a Material overrides parameter (of the same name) defined in a Effect, Technique and RenderPass, but are overridden by parameters in RenderPassFilter and TechniqueFilter.
