Good to see you got it fixed, or post-worked it away ;-) 

Couldn't get back to you sooner, my router has been on the blink. Grrr.... 

One guess might be that a transmap either got overwritten or replaced. I've been saving my shaders for the big project for each prop/set/character in a separate folder and noticed that it only saves one copy of the settings if the prop or even a texture map is repeated when I saved the whole shader set in one folder. It's merely a guess though! 

By the by Paolo, I'm not sure where it is happening, but I think it's the 'save scene' command in Reality that will save duplicate Reality Data nodes to the scene in Studio. I was having shader issues on one run and went to "show hidden nodes" in studio and found 9 copies of Reality Data. Could be a Studio fluke too, as its so crash-happy that I save constantly.
