I have a student who could not generate a shading mask, and instead got an error saying (paraphrasing):
Solution exception: Method not found: “Rhino Geometry. Brep Rhino.Geometry.Brep.CreateFromMesh(Rhino,Geometry,Mesh,Boolean).”
This error happens when the "Mode" input is set to "Shading Mask." There's no error when this is set to "Horizon". Both the Rhino file and gh files work on mine and others' computers, so that's not the issue. The student is running the tool with a current educational license.
Any ideas? Thank you for your help!
