When I tried to create an override on the original material I found I didn't have access to the ICE Attributes generated by my ICE Tree anymore and when I tried a Boolean Switch to incorporate my constant shader branch in the original shader, to override merely the switch, I found I lost my ICE attribute also... (i.e. the ICE attribute I needed didn't appear in the drop-down list of my attribute shader node anymore...)
What am I doing wrong here?
(Please be gentle
, still an ICE and Passes newbie I'm afraid) ;)
And to that annoying moderator (Hirazi Blue!!!
) who keeps moving threads: I found this one tough to place as it involves ICE, Passes, The Render Tree and the future intention to use it all in the FX Tree. I decided to post this in "Rendering" as it has been the Render Tree where the ICE Attributes went missing...And we don't want this community to be only about ICE, now don't we???
