Running 2012x64 with plugin version 1.20.1
NVIDIA Quadro K2000M (9.18.13.2092)

When I select a scene the Octane window briefly opens but then Revit immediately crashes. I have tried many files including the Revit example scene. All crash all the time. What am I missing? Thanks.

Hi

Can you load an obj file into Octane Standalone and render?
What Nvidia driver version are you running pls?
What compute model is your card? (this will be displayed on the Cuda tab when you start the plugin in Revit).

Yes I can render in the stand alone.

Operating System: Windows 7 Professional, 64-bit (Service Pack 1)
DirectX version: 11.0
GPU processor: Quadro K2000M
Driver version: 320.92

Compute Model is: 3.0

Thanks for your help Paul.

Updated Driver to 331.82 and there was no change to this issue.

Driver version 331 seems to be buggy for some users, whereas 320 and 327 are good.

I haven't heard of anyone having the problem you are getting before - so throwing some ideas out there....

1) Does the crash happen if you add a single blank wall to a new Revit scene and render?
2) Also, try the above with the Direct Lighting kernel - does that help?
3) Which actual version of the plugin are you using? Have you tried 1.20.1.20
4) Are you on the English version of Revit?
5) How many samples are being rendered before it crashes? Do you see the first render image?
6) Did you install the demo version are try that first? If so, make sure it was installed prior to installed the commercial version (uninstall via the windows Control Panel)
7) If you have NOT tried the demo version, can pls uninstall the plugin via the control panel, then install the latest demo from the Autodesk Store and see if that works (it contains some very minor fixes not yet in the commercial version).

1)I built a single wall and was able to render in the Octane Viewport.

Crash appears to happen with other files during the "analyzing scene element" phase, the Octane viewport never actually opens. I have tried it with three of our projects and the Revit example file and all crash at the same point.

2) Still Crashes with the Direct Lighting Kernal.

How much RAM does your PC have pls?

32G

Well it's not running out of memory then!

Could I pls trouble you to email me the journal file resulting from a crash - it will be in C:\Users\[username]\AppData\Local\Autodesk\Revit\Autodesk Revit Architecture 2014\Journals.

I have a theory that the crash is due to an issue occurring in the load process, and the plugin is trying to display the warning/error, however because the load process is multi-threaded, the displaying of the error is being attempted in a thread than is not the main Revit thread. The journal file will confirm this.

Are you on the English version of Revit?
