OTOY Forums

I'm using the latest Octane (downloaded today), with Revit 2017, and receive the following message when trying to start a render:

Exception starting render : System.NullReferenceException: Object reference not set to an instance of an object.
at OctaneRenderPlugin.CameraChangeMonitor..UpdateValues(View3D view)
at OctaneRenderPlugin.CameraChangeMonitor..ctor()
at OctaneRenderPlugin.RenderManager.CreateCameraMonitor()
at OctaneRenderPlugin.RenderManager.StartRender()

Octane Release number is 3.6.5.46
Revit Release number is 17.0.1128.0 / 20170419_0315(x64) / 2017.2.1.

I'm also seeing a TimerTickEvent error (see attachment) when Octane starts rendering. If this error occurs, Revit crashes.

Any idea what's going on?

Thanks,

Hi - is this problem happening on all scenes, or just one? What was the previous version you had installed?

Paul

It happens on multiple scenes, but so far only in this one file. I think I have been using the same (most recent) version for a while - I just updated it today because of the error, in the hope that it was a configuration problem of some kind. I was not able to get any of the views I tried today to render from this file.

I'll try to do some experiments tomorrow to see if there is some kind of pattern. I have done an audit on the Revit file: no errors were reported by the audit, but the Octane problem persists.

Would it be possible to send me the .rvt file pls? I need to determine if it's a specific issue with that file, or a general bug that has been introduced to the plugin. Those errors are indicating there is a problem with the Revit Camera/View.

Paul

I sent a PM with a link to the file. Let me know if you have any trouble accessing it.

Thanks,
Tim

I have investigated this issue, and it is a corrupted Revit View or sun settings. About 50% of the time, even without Octane loaded, just selected the views which cause this error will lock up Revit. So there are issues with those Views, and they should be recreated. I have added some checking in the next release of the plugin which will notify you of this problem.

Thanks - I came to the same conclusion, as I discovered the views won't render using Autodesk's cloud renderer either.
