Anisotropic material still not supported by the sim

Hello everyone, since the release of msfs there is a material included in the
3DS max plugin wich is not supported by the sim : “Anisotropic Material”. This
would add some realism in some special textures, like on the blur propeller
reflections, circular metal pattern etc… So is Asobo planned to fixed this ?
Someone told me that it was a problem from the core sim and that it would be
fixed. That was several months ago. That would be awesome to use this material
in msfs. Regards
