	/** The default behavior in Irrlicht is to disable writing to the
	z-buffer for all really transparent, i.e. blending materials. This
	avoids problems with intersecting faces, but can also break renderings.
	If transparent materials should use the SMaterial flag for ZWriteEnable
	just as other material types use this attribute.
	Use it like this:
	\code
	SceneManager->getParameters()->setAttribute(scene::ALLOW_ZWRITE_ON_TRANSPARENT, true);
	\endcode
