OBS v27 Mac Virtual Webcam doesn't show up in DirectCam (Adultwork player) or in Whereby but works fine with LUTs in Skype. No idea what to try next.

[OhHiThere]

I've used the set up wizard to configure for virtual webcam use, OBS works fine in Skype with two devices, am using Mojave 10.14.5. Can't think of anything I've missed as the setup for v27 looks really simple and it works in Skype. Any help would be appreciated.
