@rcmcdougle make sure RhinoRenderCycles and RhinoCycles plug-ins are loaded. These are Rhino core plug-ins that hold the SDK the GhShaderNodes plug-in uses. Or alternatively remove the GhShaderNodes plug-in.

4

RhinoCycles is loaded… I don’t see RhinoRenderCycles in the list of plugins, just RhinoRender. Am I missing something here?

5

Rhino Render is correct, especially if the assembly is RhinoRenderCycles.dll.

Anyway, I haven’t kept GhShaderNodes up-to-date with Rhino 8, and I won’t be doing so in the near term.

Best to remove GhShaderNodes.

6

How do I remove that? I can’t seem to find it anywhere.

7

Searching my C drive, I do not find RhinoRenderCycles.dll. I running Version 8 SR11
(8.11.24254.15001, 2024-09-10)
Commercial
Where could I obtain that dll?

8

I see now that when I click on Rhino Render in the plugins list the description shows as RhinoRenderCycles.

@rcmcdougle you can run the Rhino command GrasshopperIgnorePlugin. This will pop up the folder containing Grasshopper plug-ins. Select the .gha file for GhShaderNodes. Do this before starting Grasshopper.
