Top view showing the placement of the VRAY Lights. Since the lights are double sided the direction of the arrows are kind of meaningless.

For this particular scene make sure the VRAY Light is set to double sided so that it will emit light on both sides.

Click the buttons to assign a material for the front and back materials. It is best if these are VRAY materials. If you already have VRAY mats made simply drag them into the area in red. (Front or Back)

Note: The front material for the 2 sided material may not necessarily be the front portion of the geometry you are applying the 2-sided material to. You may need to swap the front and back material to get the desired result.

Once the the front/back materials are in place simply adjust the translucency to get the desired result. For this I like to use a shade of grey rather than a numerical value.

In this particular scene the front and back VRAY materials have bitmaps in the diffuse slots. Click the "M" in the red area to browse to the specific bitmap you want to use. The reflection/refraction values will change depending on what you are trying to achieve.
