Hi again all,
I solved my linked-colormap problem when rendering multiple volumes (thanks
Utkarsh, using separate variable names worked great!). My next issue is
this: can someone explain when colormap transparency is enabled? In some of
my data views, the opacity option is grayed out (for example
Gray,
Currently ParaView supports changing the opacity in colormaps only for
volume rendering. When rending slice or points as surface or anything
other than volume, opacity will be fixed to single value that can be
set on the Display tab.

Hi Utkarsh,
Half-progress. So, I can display a variable-transparency volume rendering
(in this case of a head MRI, set so that the 0s around the head are
transparent). I can then add a .vtk surface, and I can sorta see "both"
datasets when opacity on the surface is set to 1.00 ... the grayscale vo
Ah! Now you are getting into murky waters :). Volume rendering
together with translucent geometry is difficult thing to do with
OpenGL. You need a full fledged ray-tracer for that to work correctly.
You are correct, in VTK/ParaView, the geometries are rendered
(including translucent geometry) befor
