Most render passes are broken?

Okay, my problem is, All my passes render out black,
I tried using a multi channel EXR to get the passes out, then I fusion and nuke and AE I could see that all the passes where just empty with 0 value in them !
And this is happening on every scene I've tried, I'm resorting to rendering my Z in info channel...so stupid !

I hope it's just a mistake I've made or something I don't know about the BlenderOctane workflow, if this is really a limitation of he blender version,
OTOY need to announce that in big red warning that a major feature doesn't work yet,
the lack of support for Blender plugin is staggering, impossible to find any advanced info on it, half of the settings are conflicting and cause the render to just hang eternally..

Please let me know if you have any info, I'm really stuck in my project because of this passes Issue.

Hi LaBaguette, sorry to hear that. hey did you by any chance had the rendered view on in the 3d view prior to rendering all those passes?

Hey LaBaguette, I have recently been experimenting with render passes and they do work for me in Blender. However, I did notice some issues with the way Octane (both Octane Blender and Stand Alone) possibly write out the Multilayer EXR files. I posted this earlier today - don't know if your problem is similar:
viewtopic.php?f=23&t=51571

Have you tried the following:

Viewing the Multilayer EXR file in Photoshop with the ProEXR plug-In to see if in fact the layers contain data (you can adjust the exposure value if the images seem all black or all white)?

Or have you tried outputting the render passes to individual EXR files? If so, are there also problems with your single files?

Nope, rendering doesn't start at all if the view port is on rendered

@Pegot same issue as you man !
both fusion and nuke and AE display 0.0.0 RGB info, (AE has ProExr built in, so yup, doesn't work either )

Okay I checked again and somehow it seems like the Z pass works, now I double checked with previous versions of my scene, the only thing I changed was enabling "Distributed ray tracing"
and I couldn't see in the manual any mention of it, what does it do?
