Hi, the RGBtoBW node vanished between r40960 and r40962 (r40961 doesn't build for me so I can't say if it's there) and is still not present in r40985. I can't add it anymore via Add -> Converter -> RGBtoBW. It still works as usual if it's in a material from an old file. Where did it go? :) Thanks, Sanne
