Anisotropic Material Node

Is there a material node in Unreal Engine that is the equivalent to the anisotropic node in Blender’s Cycles rendering engine?

No, but there is experimental material setup that uses TemporalAA dither to simulate similar effect. You can find it in ContentExamples project, map Material_Experimental.

“Hair” shading model also uses some kind of anisotropic specularity, so maybe it would be interesting for you also.
