Iray Uber Shader: One more time!Warning! This tutorial is not intended to cover each of the shader's properties. That's what the original product documentation is for.

After some googling I've found two tutorials on the matter and even one half-baked vaporware script. The approach used in tutorials was more or less the same so I've followed the excelent explanations of SickleYield and got my Olga as Genesis 8 in minutes.

The problem that each of these steps brings new errors and those do accumulate. Thus w
