Maybe, I also couldn't compile some of my old shaders, I had to disconnect some nodes in order to make it work.
Same here, can't use hotkeys, no copy/paste, what so ever
are you leaving opengl2 on?
Yeah, i figured it about the desaturate. Thanks for the quick response
I actually mean't the saturate being a "levels" in photoshop, just the way the clamp0-1 works. I don't see a need for saturation node.

Hey, i restarted my PC, and it worked again, I was using 4.2 as well. weiiiird.

nevermind, I found a way of doing through light attenuation, lerping through values and using emissive. But still. I meant receive!
