示例1: prepareMaterialInstance

	//------------------------------------------------------
	void MaterialService::prepareMaterialInstance(MaterialPtr& mat, unsigned int idx, int tag) {
		if (tag < 0) // Should not be here if the polygon is sky textured
			OPDE_EXCEPT("Non-instanced material instance requested", "MaterialService::prepareMaterialInstance");

		mat->setReceiveShadows(true);

		StringUtil::StrStreamType lightmapName;
		lightmapName << "@lightmap" << tag;

		Pass *shadPass = mat->getTechnique(0)->getPass(0);

		if (shadPass->getNumTextureUnitStates() <= 1) {
			// Lightmap texture is added here
			TextureUnitState* tex = shadPass->createTextureUnitState(lightmapName.str());


			// Blend
			tex->setColourOperation(LBO_MODULATE);
			// Use 2nd texture co-ordinate set
			tex->setTextureCoordSet(1);

			// Clamp
			tex->setTextureAddressingMode(TextureUnitState::TAM_CLAMP);


			// Switch filtering off to see lmap pixels: TFO_NONE
			tex->setTextureFiltering(TFO_BILINEAR);
		} else {
			// There is a definition of the lightmapping pass already, we only update that definition
			TextureUnitState* tex = shadPass->getTextureUnitState(1);
			tex->setTextureName(lightmapName.str());
			tex->setTextureCoordSet(1);
		}
