Question / Help Chroma Key's override each other?

[PrinceVinc]

I wanted to try if I can set 4 Chroma Key for every corner of my Green Screen.
But this doesn't seem to work as it should.
I tried the Keys Separately to check if they cover the spectrum I want, but if I activate them all, some Areas show the sparkels again. If I only activate the Key that should cover the Sparkles it does, but as soon as i activate the other Keys again it does not do it anymore. What could be the Problem?

I have keyed with 2 and 3 keys successfully. I haven't tried 4 though.

What happens when you try 2 or 3 keys?

I just tested a little more. Could it be that the order affects the Chroma Key?
(Same result with 3)

How did you make sure that all 3 Actually work as you think?

Yes all 3 work. You have to key with #1 first, then turn it off, and then set your key on #2, then disable that, then set your Key on #3, then disable it.

Then you enable key #1 and tweak it. Then enable Key #2 (while #1 is still enabled) and tweak that, and repeat for #3. keep in mind that each key affects the key above it even if only slightly.

This means you might have dropdown a key and re-tweak it again.

Ah! So they affect each other from top to bottom? That's the thing I needed to know thx :)
