OSPRay Fails to Render DataSet in VTI file in ParaView 5.2.0 with VolumeMapper's Input has no scalar array
load vti file like that attached 30cubedSample.vti, click apply in in properties box. Select Pressure (or anything or don't) in scalar filed drop down box. Select Volume Representation. Then click "Enable OSPRay" in the properties tab. Error Message: ERROR: In /Users/kitware/buildbot-slave/b99e1795/source-paraview/VTK/Rendering/OSPRay/vtkOSPRayVolumeMapperNode.cxx, line 107 vtkOSPRayVolumeMapperNode (0x7fe4934a3c80): VolumeMapper's Input has no scalar array!
You can't seem to select a scalar array directly out of the reader. You can use the calculator to pass the arrary, and that will work and get volume rendered...
