I am going to make a fence model. I need to know which is more efficient.

1 alphatest, no cull texture for all, effectivly doubleing the polycount (only a quarter of the polygons need to be transparent)

Or 2 textures, 1 with alphatest and no cull. Doubling the drawcalls.

Which is most efficient.

I expect the polycount to be 80-120
