curtain by opacity map = disaster ! ?

i try to be close to real world and create curtain by real fabric opacity map

the result is lotsss of noise that cant be clear

i guess is because all the rays need to travel thru the tiny holes and get lost

even if i put portal outside and exclude the curtain is still not go well

what to do? 2 side material maybe look ok from far but not for close up

any great solution for curtain?

Try setting the VRayMtl opacity mode to "clip" and see if it helps.
