Splitting out a multi channel matte

Hey there! What’s your favorite way to split out an RGB matte? I use a mono node for each channel but I seem to recall a matchbox shader. Was it just a dream?

I’ve always done mono node…not sure if there is a Cryptomatte Maker…that’d be nice.

If its for Baselight/grade its POSSIBLE you’re gonna have a bad time if I recall as Baselight doesn’t support RGB mattes (at least if my memory serves me right).

I use combine to create RGB mattes. I’m trying to figure out if there is a tool like an inverse combine to break them back out into black and white mattes…

the best one that I have used is md_multi from the md_shaders collection, basically 6 inputs with blend modes and on/off toggles to combine them.
