Hello,
I can't find a way to render object mask passes.
In c4d you just give a layer ID to the object you need the mask of, then you activate render layer mask in the pass tab by checking the ID number you need (from 1 to 24).
I tried everything in Houdini, including $OCTANE_LAYER and $OCTANE_PASS tokens, Octane doesn't gives me any mask.
I guess I am missing something obvious there, the doc is really not precise at all.
Thanx a lot
Jérôme
