Hi
I am running SR12 build 50810, and the current version of the plugin was compiled with that version’s RhinoCommon. The current Rhino demo version appears to be 50810, so Digitaline, can you pls double check that you are running build 50810 pls?
What Vnidia driver are you running? 353 and 358.50 are the best. 361.x appear to be buggy.
Have you previously installed the Octane plugin on that PC? If so, and if it was via the .exe installer, you need to uninstall that version first, then install the new version via the RHI.
Are you able to post a screenshot of Tools->Options->Plugins->OctaneRenderForRhino->Properties pls?
Also, is it possible you are running 32bit Windows? Octane is only supported on 64bit OS’s.
