The vtkLookupTable::SetTable() results in bad out-of-range mapping
It was reported that when the SetTable() method was used to provide an array (4-component unsigned char) for use as the lookup table, the scalars that were beyond the TableRange (either above or below) would be transparent (probably with a value of (0,0,0,0) ). This seems to be true whether or not the AboveRange or BelowRange colors are used.
This problem occurs, at least, for VTK 7.1 and for the master head.
The following example demonstrates this problem:
