I had that problem too. But my work around was disable "Start after beauty". Now u can renderout the masks.Hello, Aoktar.
I have a problem in new version 2.21.1, that wasn't before in 2.20.0 RC2 in the same scene.
In sequence rendering, after render beauty frame and beauty passes, octane starts to render other passes, including layer mask. And octane can render layer mask forever, without any progress, untill i stop it manually.
Thanks Ahment for the quick update and the memory fix!!!!!
