Jinak vlastnosti materiálů najdete tako v helpu u maxíka. ::)

Material IOR Value
Vacuum 1.0 (exactly)
Air 1.0003
Water 1.333
Glass 1.5 (clear glass) to 1.7
Diamond 2.417

In the physical world, the IOR results from the relative speeds of light through the transparent material and the medium the eye or the camera is in. Typically this is related to the object's density; the higher the IOR, the denser the object.

You can also use a map to control the index of refraction. IOR maps always interpolate between 1.0 (the IOR of air) and the setting in the IOR parameter. For example, if the IOR is set to 3.55 and you use a black-and-white Noise map to control IOR, the IORs rendered on the object will be set to values between 1.0 and 3.55; the object will appear denser than air. If, on the other hand, your IOR is set to 0.5, then the same map values will render between 0.5 and 1.0, as if the camera were under water and the object was less dense than the water.

Here are some more IOR values for various materials:

Sodium Chloride 1.530
Sodium Chloride (Salt) 1 1.544
Polystyrene 1.550
Quartz 2 1.553
Emerald 1.570
Glass, Light Flint 1.575
Lapis Lazuli 1.610
Topaz 1.610
Carbon Bisulfide 1.630
Quartz 1 1.644
Sodium Chloride (Salt) 2 1.644
Glass, Heavy Flint 1.650
Methylene Iodide 1.740
Ruby 1.770

Vytvoril som objekt ktorym presnejsie a jednoduchsie vytvorite potrebny material. V baliku sa nachadza aj samotny material SSS.
Pozor!!! Bol vytvoreny vo verzii vray 1.50.17 RC5, a pravdepodobne budete potrebovat tuto alebo novsiu verziu. V sucastnosti je dostupna ako v 32bit tak aj 64bit verzii.
