In this particular example, I have chosen to show how to create a lamp shade material using the “vray 2 sided material”, but you can create other type of similar materials like translucent paper, thin cloth, etc., following the same method.
1) Select your geometry and apply the vray2sidedMat to in, in the material editor.
2) Choose a light grey for translucency. A black value shows the front material (no translucency), while a white value shows the back material (100% translucency).
3) Click on the front material, and assign a vray material with the desired maps for the diffuse and bump slots. Do not assign a back material; leave that slot un-ticked.
4) Place a vray light (sphere) in the center of the lamp shade and scale it vertically.
5) Experiment with the vray light size and multiplier, and the translucency parameter until you obtain the desired result. For this particular scene I used a vray light multiplier of 8, and 201, 201, 201 for the RGB coordinates of the grey (translucency control) but these particular settings may vary depending on your scene, lighting rig and rendering setup.

nice tutorial…….helped me a lot
thanks
I am glad it did! Thanks for the feedback!
Thank u somuch!, i am looking for this type of material
Appreciate you post. My buddy advice to visit you. Good thing. Added in favourites! Want to read your blog more and more!
thanks man, i would like to know how to add refleccions to te material, like a falloff or something, thankiu very much !

This brings a new perspective on things, I realy like the effect
Very Very nice tutorial. thanks alot……..
for this tutriol you deserve a beer.
thank you
Many thanks!
The “beer thing” is just a form of donations through paypal… however, nobody has donated anything so far.
hi! i am new to Vray, i wonder why my Vray 1.5 sp2 has no SUN, IES, and even vray 2sidedmat as well, is there anyone can help get a full version? and if u don’t mind, could you attach some tutorials for exterior day/night scene.. i just hope that there could be someone who can help me solve my problem..
thanx to all!.. =-)
I think you should ask the customer support of chaosgroup or the dealer from where you bought the vray… I’m afraid that nobody else can help you with that.
Regarding the tutorials, I have already posted a tutorial about night exterior illumination, and there will be more to come.
Thanks for visiting!
Very nice tut. Helpful
Amazing Tutotial, and very benifit, thanks you very much.
i like here.. this is a nice place.
Sir Alex mincinopschi,
i just wanna ask how to make a seethrough curtain? cud i use any texture? if so, then what components shud i adjust?
A light inside this kind of material doesn’t create any shadows on the outside of the lamp, or am I wrong? Or has it something to do with the material settings..
Actually it does create a subtle shadow. Here is a very quick test I did with the same material settings as in the tutorial above:

@ johaim
A see trough curtain is a little more complicated. You have to use a combination of refraction and 2 sided material.
If you just want a translucid curtain, than you can use any texture you want, and adjust the translucency in the 2 sided material parameters.
Awesome Tutorial……really nice…thanx.!
Hi there !
thanks for that tutorials ..but i am wondering why do you scale the light .. as i try to scale .. its bigger in the viewport but as no effect on the render…
i am trying to do a rectangular light
thanks for helping
Patrick
Hello Patrick.
Scaling the light actually affects the area that is lighten.
For example, the tall lamp (in the first image of this post) has a scaled vray light inside. If I hadn’t had scaled it, it would have turned out as a light bulb inside, and not as it is at the moment.
i dont know why its not working for me
do you have a email where i can send you my render
thanks

I love this.strait to the point with no ambiguity.
thanks alot for your help
i did this using the tip.it came out quite nice but i didnt scale the vray light.i used photometric light because i think it simulates real life light better.hopin to get better w time

This creates some changes in my renderings,
Thank, thank you very much for this tutorial,
nice
thank u a lot for this powerful tutorial.
Hi, i wonder if there is a vray dirt setting to the whole scene rather than each material. would help heaps if anyone knows how….if….
thnks
Thanks man
U made me discover how to create translucent acrylic the easy way
