Pretty self evident via the title, but the new multimatte channel isn’t being written to the vrscene file on output. Zip, nada zilch mention of it in the vrscene file, first noticed today because Deadline wasn’t parsing that render channel. Confirmed with a completely fresh and default file in 36002 with nothing but a box.
You are correct, I noticed that too late.
We will resolve it as soon as possible.

Konstantin
