Reader backlit paper

I want to express Japanese « Shoji »(paper screen).
Light is transmitted, but the paper is completely milky and the scenery on the other side cannot be seen.
I set Opacity to 70 and Shininess to 0, and changed the Refraction, but they all looked like Bump glass.
Is there any good way?

1.Opacity 80_Shininess 0_Refraction 1_Bump 100
2.Opacity 80_Shininess 0_Refraction 3.5_Bump 100
3.Lite emitter 60(LIteEmitter and Opacity may not work at the same time.)

The shadow doesn’t have to appear so much.
