tyFlow Cryptomatte workflow

[betamax]

I can't get Multimatte to work correctly with Tyflow either.
If you set a Shape operator to use a random Mat ID between 1-3 for example, and choose IsMatID in the Multimatte render element, it renders black.

I have a feeling that Cryptomatte and Multimatte use the same coding which Tyson mentioned he hasn't looked into yet.
