OSPRay rendering does not update when time-dependent molecular data is changed
Doing a normal OpenGL rendering of time-dependent molecular data with either the vtkXYZMolReader2 or the vtkVASPAnimationReader works as expected. However, if turning on an OSPRay rendering pass, the image never changes when animating data with reader.UpdateTimestep().
I have found that I need to force re-rendering with a mapper.Modified() the attached python code demonstrates this TestXYZMolReader.py
