Matte Objects Tweet

[adrianr]

I've read numerous times now how object layers are the solution to this but with no examples, and no joy fumbling around myself - Can someone please provide one to show a basic hold-out matte setup as you would do in Mantra/Karma/Redshift?

Totally agree.
I feel we are lost behind.
The layers workflow (at least as in all the forums messages combined through the years) makes render out (not IPR) render each layer separately, so every matte starts from the beginning.
Dev's please, provide the solution including all the steps, not only where to look for. Why we need to search through 7 year old messages to get clue what to do?

And I wonder if the new compositing nodes can help here to create mattes? That will not double the render time
