Whats a good method to render shoji doors? You know like paper and a light shining through it

I realize im pretty much doing what u guys are doing, but at this point even if there are no shadows… my current results are 1 side lit… the other side is practically black though i still see light shining through where lights are… just looks much different with dynamic light… (on a screen thats colored white) Which makes no sense from a lighting point of view… though it works with dynamic movable lights fine.

Only thing im going to do is play with the opacity settings and see if that changes anything.
