Sorry, please ignore the first question. I know what you mean right now. But, please look at the second question: "Also, I notice that in the vtkSMUniformGridVolumeRepresentationProxy.cxx file (Servers/ServerManager/), between line 100~117, there are some code specifically related to VolumeFixedPointRayCastMapper, do I need to change these codes too?"
