Please help me with this issue. The plug-in “RhinoRenderCycles.rhp” is loading on start-up.
Once I manually try to load it from the Plug-ins folder, this is what it says: “Unable to load RhinoRenderCycles.rhp plug-in : ID already in use.”
I am unable to take renders.
Please run SystemInfo command in Rhino and post the results.
Most likely you need a CLEAN install of your nvidia driver (happening to some after windows update as of late)
Thank you for the response.
The issue seems to be solved. I found that Windows Security was blocking the plug-in from loading. The error dialogue box stated that “the author of the plug-in is unknown.” So, once I switched off “Smart App Control,” the plug-in started loading at start-up.
I am, however, posting the result of the systeminfo command below. Hope it helps.
