copy method

@override MeshGouraudMaterial copy(Material source)

Copy the parameters from the passed material into this material.

Implementation

@override
	MeshGouraudMaterial copy(Material source ) {
		super.copy( source );
		color.setFrom( source.color );

		map = source.map;

		lightMap = source.lightMap;
		lightMapIntensity = source.lightMapIntensity;

		aoMap = source.aoMap;
		aoMapIntensity = source.aoMapIntensity;

		emissive?.setFrom( source.emissive! );
		emissiveMap = source.emissiveMap;
		emissiveIntensity = source.emissiveIntensity;

		specularMap = source.specularMap;

		alphaMap = source.alphaMap;

		envMap = source.envMap;
		combine = source.combine;
		reflectivity = source.reflectivity;
		refractionRatio = source.refractionRatio;

		wireframe = source.wireframe;
		wireframeLinewidth = source.wireframeLinewidth;
		wireframeLinecap = source.wireframeLinecap;
		wireframeLinejoin = source.wireframeLinejoin;

		fog = source.fog;

		return this;
