Node instancing and other issues

Hi Everyone! I’m a new user of Nuke, so I’ve come across a few problems

1. There is a very strange thing about CC node. I set up this node to get the colors that I like, and move on with working on the script. After some time, this node starts to produce different colors then setuped before, and I have to change only one value( ie. saturation) by 0.001, to get the colors back. It sounds totally crazy, maybe someone knows what I mean.

2. I imported some simple geometry and camera, to render B/W masks. But AA guality is very poor, even if I set High AA quality in scanline renderer. Any way to increase AA in scanline renderer ?

3. What would be a way to make node instance ? I mean, few Grade nodes, but to controll only one, and settings would affect all of them. I suppose expressions could handle this, anyone has a example for this ?

4. Is there any database or user community that shares Python scripts for Nuke ? I’m not familiar with scripting yet, but I already would use it a couple times. A great example is ScriptSpot for 3ds users – tons of great free scripts.

Thanks for help folks!

cheers,
TAS 🙂
