GPU based Volume Rendering always use the first data array for coloring
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The problem arise when volume rendering a cartesian-grid dataset with multiple scalar arrays. If the GPU based volume rendering is selected, it does not matter what scalar array is selected for coloring, Paraview always use the same one. For example, if there are Temperature, Pressure and Velocity magnitude, Paraview will always show the Temperature attribute, even when pressure or Velocity magnitudes are selected. All the other kinds of volume renderer (Ray cast and Texture mapping) work correctly.
This happens both on my laptop (NVIDIA GT540M / driver 306.94) and my desktop (NVIDIA GTX580 / driver 314.7)
