Nope. still didn't show up. I tried to create a subfolder category for Iray in the surface/shaders, but still nothing. I was able to pull other shaders over though. Oh well. I know where it is now.
it may just be the fact I've installed so many extra Iray Add-on's that it shows up that way for me, not sure what the glitch is.
but at least you found it and can get it to work now.
