Really like using Ivar’s Additive Keyer in Rec709. Not very useful in Wide Gamut or ACES from what I can see. Any one else using it in spaces other than Rec709?

Pretty sure it should work well in all colorspaces but you need a good matte

We are smashing ACEScg shots out now using the crok\_additive\_key. So good 🤗

Are you using it with the IBK to pull the matte?
