Blender Z depth node - depth of field

[adamrg7]

I want to try and use blender defocus node for depth of field hopefully to speed up render time instead of using octane depth of field. Also might better because i am green screening and should probably leave depth of field for compositing. But the Z node doesnt seem to be working properly. What am i missing?

Hi adamrg7,
here is another discussion about Z-depth pass in Standalone:

The same principle works also with all the integrated plugins.
Let us know if you solve your issue.
