curtain material

Can anyone tell me how to reproduce these materials (curtain) in cinema 4d?

Create a Ray-Switch material, like in the Max-Screenshot you posted?

I would like to recreate the same material, GI material and “zanaveska” material

Not sure if this is something you are after…

I suppose you want to recreate max material in corona c4d. Just add fresnel to refraction channel and tweak settings.
You can add low reflection if you want but not necessary.
Of course you need one light source ex. sunlight to make it to work.
