Summary:                    VRML Exporter disregards UseLookupTableScalarRangeOn
on LookupTables
Description: 
In its (internal) PolyDataMapper the exporter "copies" ScalarRange from the
actor (Get/Set), disregarding UseLookupTableScalarRangeOn if such done.
As a result the lookup table (colors) gets reset to the defaout range 0..1.
Remark: I do not now if "by design" the GetScalarRange shall (only) return what
has been "Sat" (diregarding UseLookupTableScalarRangeOn) OR if any Exporter
shall check UseLookupTableScalarRangeOn and go the other (now missing) way.

My Code:
contourMapper.ScalarVisibilityOn();	
contourMapper.SetLookupTable(_LookupTable);	
contourMapper.UseLookupTableScalarRangeOn();	// otherwise Mapper overwites lut
range!

and in vtkVRMLExporter:
  pm = vtkPolyDataMapper::New();
  pm->SetInput(pd);
  pm->SetScalarRange(anActor->GetMapper()->GetScalarRange());
<================??????
  pm->SetScalarVisibility(anActor->GetMapper()->GetScalarVisibility());
  pm->SetLookupTable(anActor->GetMapper()->GetLookupTable());
  pm->SetScalarMode(anActor->GetMapper()->GetScalarMode());

i.e. no check if UseLookupTableScalarRangeOn used instead
