		<h1>[name]</h1>

		<p class="desc">
			An extension of the [page:MeshStandardMaterial] that allows for greater control over reflectivity.<br /><br />

			Note that for best results you should always specify an [page:.envMap environment map] when using this material.

		<h2>Constructor</h2>

		<h3>[name]( [param:Object parameters] )</h3>
		<p>
		[page:Object parameters] - (optional) an object with one or more properties defining the material's appearance.
		Any property of the material (including any property inherited from [page:Material] and [page:MeshStandardMaterial]) can be passed in here.<br /><br />

		The exception is the property [page:Hexadecimal color], which can be passed in as a hexadecimal
		string and is *0xffffff* (white) by default. [page:Color.set]( color ) is called internally.
		</p>


		<h2>Properties</h2>
		<p>See the base [page:Material] and [page:MeshStandardMaterial] classes for common properties.</p>

		<h3>[property:Float clearcoat]</h3>
		<p>
		Represents the thickness of the clear coat layer, from *0.0* to *1.0*. You can use clear coat related properties to enable multilayer
		materials that have a thin translucent layer over the base layer. Typical examples for this model are car paints or acrylic.
		Default is *0.0*.
		</p>

		<h3>[property:Float clearcoatNormalMap]</h3>
		<p>Can be used to enable independent normals for the clear coat layer. Default is *null*.</p>

		<h3>[property:Vector2 clearcoatNormalScale]</h3>
		<p>How much [page:.clearcoatNormalMap] affects the clear coat layer, from *(0,0)* to *(1,1)*. Default is *(1,1)*.</p>

		<h3>[property:Float clearcoatRoughness]</h3>
		<p>Roughness of the clear coat layer, from *0.0* to *1.0*. Default is *0.0*.</p>

		<h3>[property:Object defines]</h3>
		<p>An object of the form:
			<code>
				{

					'STANDARD': ''
					'PHYSICAL': '',

				};
			</code>

			This is used by the [page:WebGLRenderer] for selecting shaders.
		</p>

		<h3>[property:Float reflectivity]</h3>
		<p>
		Degree of reflectivity, from *0.0* to *1.0*. Default is *0.5*.<br />

		This models the reflectivity of non-metallic materials. It has no effect when [page:MeshStandardMaterial.metalness metalness] is *1.0*
		</p>

		<h3>[property:Float transparency]</h3>
		<p>
		Degree of transparency, from *0.0* to *1.0*. Default is *0.0*.<br />
		
		Thin, transparent or semitransparent, plastic or glass materials remain largely reflective even if they are mostly transparent.
		
		The transparency property can be used to model these materials.<br />
		
		When transparency is non-zero, [page:Material.opacity opacity] should be set to *1*.
