Hi Tim
Would it be possible to get some info from you pls as per the requirements listed in
http://render.otoy.com/forum/viewtopic.php?f=61&t=37775 (ie. plugin version, Revit version, NVidia driver version etc).
Also, does Octane Standalone (1.32) work for you?
Does it crash on every scene, or just certain scenes?
If you set the kernel to Direct Lighting, does it crash?
What was the version version that worked for you?
I had a look through the log file you sent me, me it looks like the crash is happening prior to the plugin trying to load any of the geometry.
