Mads:

It was quite fun to see that 2 days after publishing the CubeKeyer post Nuke 10 was announced with a keyer for NukeStudio. And since Nuke 10 is so close, i don’t see a reason to release mine.

I totally disagree. I think Mads should release his version of the CubeKeyer. Mads thanks for a GrainChecker. Even the artist with the most keen eye cannot match grain to save there lives. Even with the Regrain node in NukeX, most artists don't even know it's wrong.
