[Sidefx-houdini-list] Rendering DeepExr for Nuke Comp

Yeah... just use Deep Resolver to Deep Camera Map and change the DCM 
Filename to a .exr and you should technically get a valid deep exr 
render. Not sure why it's not working.

What you might want to do once you got your set-up working in order to 
get better compression for your deep exr is to expose the "DCM Z-Bias" 
and "DCM Compression" parameters so you can tweak the sample merging 
options. That can really help lighten up your file size. You have to go 
to "Edit Parameter Interface..." and go into the "Render Properties - 
Mantra - Deep Output" and add them to the Existing Parameters to expose 
them in the interface. Adjusting these can really lighten up your deep 
exr file size and really accelerate the deep processing speed in Nuke. I 
highly recommend it to have a good workflow.
