Hi! How can I get smoke to appear in the zDepth channel in Maya using either Mental Rey or Arnold? Cheers,
Hello,
Please let me know if this thread about mental ray helps: viewtopic.php?f=16&t=1595&p=8762&hilit=depth#p8762
Depending on the case, it might work or might not work as mental ray does not know support atmospherics to write to its image bufers.
As for the Arnold - it also does not supports volumetrics and there is no workaround.
Thank you.
