Troubleshooting Octane

For whatever reason Octane seems to "hang" on "Updating Scene in GPU" (It was working fine before). It acts like it's working (doesn't hang the machine), but just sits there. I've looked at the logs and everything seems normal. Even when I close the window (I still have the ability to use LW) it closes as if nothing's wrong. And the logs have no data between when it "hangs" and when I close the window. Crazy thing is that F9 renders fine.

I've been working most of the day, and it's been fine. I tried previous versions of the plugin, I've tried simple scenes and complex scenes. Nothing seems to get it to work. I've turned off Network rendering (I have another box with 4GPUs). I'm at a loss as to what to do. I'm hoping it's some stupid switch I flipped inadvertantly...

EDIT: Ok, that was weird. I had a thought to click on the the GPU buttons that turn a GPU on/off (I use three of the four on my workstation to keep windows zippy) and clicked the fourth GPU on and things started to render. I'm sure that's why F9 works because it uses all GPUs to render. Hmmmm...now I have to figure out why that is...

Hi,

Hmm, this is really a weird issue. If you find any clue about why this happens, please let me know. I can't figure how to reproduce this problem here.

What LW and plugin versions are you using?

Thanks,

will do. I'm using 2015.3 and 3.08.1.0. Thanks for looking into it!

EDIT:

Seems to still happen. The GPU that I'm using for windows is a 1080ti and the other three are 980ti's. I'm using the 980ti's for rendering but the render won't move from "Loading in GPUs" until I click the button that enables the 1080ti. Don't know why that is, but haven't had to do that before. I'll try to downgrade the plugin to see if that fixes the issue.
