Glad you like it. I'll pass that on to the folks who worked on it.
Haha. We do need a bit more positivity in the forums!
Someday, I'd really love to know the math behind how it works, but right now, I'm just going to say: it rocks.
Did you know you can apply Keylight, Key Cleaner, and Advanced Spill Suppressor all in one go and in the right order with an Animation Preset? Check it out!
As a matter of fact I did! But I've actually taken to using Key cleaner a lot with things that aren't generated with Keylight. I've used it to clean up procedurally generated mattes, mainly made using "Extract", and even to add back some fine organic detail to roto mattes!
