Exclude/Include lists for reflections/refractions in Materials

[pokoy]

I guess this might be complicated, but it's a very nice option to have the ability to exclude/include objects from/for reflections and refractions in the material. It's  possible in Brazil for example (fRender too...?) and is something I'm missing every time I mess around with Vray.

Hope it is possible to implement!

This is probably too much fake for Corona...
