Arnold, Zdepth Pass, and COPS May 22, 2017, 2:39 p.m.

Hello everyone,

I'm John Draisey, a 3D generalist who has used Nuke for compositing the last few years. I recently started diving into Houdini's Compositing Ops and it looks like there's a way to do zdepth defocus on EXR files. But I'm having trouble using the Arnold Renderer Zdepth pass to get camera bokeh. The distance information when I activate the pixel inspecter is in the 30~60 Thousand range rather than the 0-1 range that I've seen in this tutorial:

If I can do my AOV compositing in Houdini, that would be a big win in terms of workflow. Does anyone have any tips on dealing with the Arnold Zdepth pass in Houdini?

I attached a multi-layer EXR frame as an example.

Thanks all!
