I'm displaying my simple 3D data set on a structured grid. With a 4-component unsigned integer vector on each point, and after turning off the "map scalar" option in the displays, I have been able to present my data with the given RGBA values in the "surface"
or "points" mode. In the "volume" mode, however, this breaks down and the colors & opacity are still mapped from the individual components of the 4-vectors as scalars.

Am I missing anything? Or is this a known issue? I'm using ParaView 4.3.1, Thanks.<o:p></o:p></p>
