Difficulties with transparencies

I’m mapping an image with alfa transparency in a plane. The results concerning to shaded and lighted face is unexpected:

The good one with Cycles. a face lighted and another shaded

With Armory: Two faces lighted or two faces shaded

My work around was extruding the plane to get a narrow mesh with the image mapped on two faces.

But ¿is there a smarter solution for this?

transparency 2.blend (1.3 MB)

Does it still happen if you set the material as “two-sided” in the material tab? Untitled-1

Oh, yes.

Material > armory pros > two sided
Material > armory pros > aloja test.

I loaded up the .blend and it seems fine:
Eevee: grassEevee

the ligth has disappeared in runtime?
