Depth of field broken with Cuda in vray_adv_35701_maya2016_x64_27226

[FIRELION]

Jumped up to the latest nightly for testing and it looks like depth of field isn't working under Cuda. I tried setting it both in the render settings as well as in the physical camera tab, but no luck. It's fine in CPU mode, and shows up during light cache generation (cpu of course), but in both production and ipr cuda rendering it has no effect.

Hm, seems to work fine here https://www.youtube.com/watch?v=xlOO...ature=youtu.be

Anything more specific ?

Here's an attachment of a basic setup. I rolled back to vray_adv_35501_maya2016_x64_27164 to see if that would fix it, but it doesn't seem to. With this scene, if I switch to CPU mode, I get DOF in the render. In Cuda mode, it's razor sharp. The only difference between these two images is switching the modes.

I wonder if it's related to a recent Nvidia driver update, as I don't recall seeing this issue on 35501 a few weeks ago. I'll try rolling back my driver to see if that's the cause.

Fyi, Maya 2016 SP5, Windows 10.0.14393, GTX 1070 on 378.66

Rolling back Nvidia drivers didn't help. I've also tried this on a few other machines with similar configurations just to make sure it's not a ghost in the machine, and the problem persists. Even if I go back several nightlies versions, I'm still seeing the same issue.

I think I've tracked it down. If I setup the camera to be a physical camera in Maya and set my dof settings there, it looks like it's working. If I'm just enabling DOF in the render settings overrides, it works fine in cpu mode but not in cuda mode. Easy enough to workaround for now, but it would be great having the render settings overrides working as well to avoid having to set iso/shutter/aperture in the physical camera.

Thanks for the report, I was not realizing we were talking about Maya.
