[ Reflections / Refractions in Mental ray]

If you have need to render specific materials with transparency in 3dsMax you can use mental ray which is designed to render with different settings high quality materials, like plastics, glass and more.
This tutorial will cover up basics for mental ray material creation and settings, first of all you need to assign the mental ray renderer in your 3dsmax render default setup dialog.change the 3dsmax default scanline renderer to mental ray
The scene will be composed of geometry, we will use simple cubes with chamfered corners, and a light emitter. The cubes need to have enough vertices to raytrace, a chamfered box with settings :

Length / Width / Height : 1 meter. Fillet : 35.0 cm.Segments : 10.
Once the cubes created you will need to place the light, for this you will need to create a Architectural material, set the setting luminence cd/m2 to 1500, and assign the material to a large enough plane in your scene, the normal vector of the plane will guide you for the light direction.

The Cubes material.
Create a Arch&Design material and assign the following properties :

Reflection : 1.0 / Glossiness : 1.0
Refraction : 1.0 / Glossiness : 1.0
IOR (Fresnel equation) : 3.68

You can then play with the Custom Reflectivity Function.
Here are a few examples :
