Ghostly Iray Shaders

Ghost-like shader for Iray (bonus for the ability to give it different colours for a true rainbow spectrum of choice - white/yellow/blue/green/purple/red and so on).
Not like the recent 'Ghostbusters' remake (too much cartoonish neon), but more along the lines of what was shown in the original, where there's an intriguing mixture of a slight emissive glow, transparency and a 'washed out' discoloured appearance.

The trouble is that's a cheat - you see only the near surface of the ghost, not any interior details or the far side, which would be very hard to implement in a PBR renderer like Iray (you essentially have to say "ignore all surfaces belong to this item behind the first encountered"). You probably need to do this as they do in the films - by layering two different renders on top of each other.
Did you try this one: http://www.sharecg.com/v/80867/browse/7/Material-and-Shader/DS-4.8-Iray-Ghost-Shader It's for 4.8, but I can see if it will work with 4.9.
That's a good one! I can hardly ever get third-party products to function in DS, though. I need to get stuff through the official shop, so that the DIM can install it correctly.
