Hello, I have problems with rendering a simple unstructuredgrid with OSPRay turned on. The UnStructuredGrid is constructed as attached, and it renders fine without OSPRay. I’ve also tested my setup and vtkSphereSource renders without a problem using OSPRay. Any soluiton/hint is appreciated.
Sincerely,
Yo-Ming Hsieh
