Connect transparency to normal direction

I'm new to Cinema 4D (come from Maya), but I'm trying to create shader that would allow me to make a series of Mograph planes transparent according to their global orientation. Specifically I am trying to simulate polarised light, so I would like the planes to be transparent if they are oriented at 0 or 180 degrees and transparent if they are oriented at 90 or 270 degrees (this is on the z axis) and smoothly in between like this:
I had some limited success achieving this using an Xpresso tag on one plane, and connecting the global rotation to the transparency of a material, but how do I do this for each individual object in the cloner? In fact, in general, how do make a material such that it affects whatever object it is put onto uniquely, or does C4D not operate like that?
