Fresnel node / incidence?

Hello!
I'm trying to render a room with some curtains and I can't find a way to change the opacity based on the incidence angle.
How would you do that?
Thank you!

what do you mean exactly ?
you want light transmitting through curtains, like cloth ?

use the diffuse transmission channel (make a new diffuse mat, connect it and hook up a floattexture to it's transmission input) and play with the values until it looks good.
