<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Nope. ParaView is just telling you that the current operation is not supported.<BR>
<BR>
Probably the best course of action is to submit a feature request to ParaView’s bug list (<a href="http://www.paraview.org/Bug">http://www.paraview.org/Bug</a>) to which you can attach an example file. I would also recommend entering the feature in uservoice (<a href="http://paraview.uservoice.com/forums/11350-general">http://paraview.uservoice.com/forums/11350-general</a>). The ParaView developers use this site to determine the priority of suggested features.<BR>
<BR>
If you have an example data set that is not too big, you can email it to the mailing list or directly to me and I can do these for you.<BR>

version 3.8 to see if there were any differences in behavior.<BR>
<BR>
In version 3.8 I'm not allowed to do volume rendering at all. When I<BR>
try to set the "Volume" representation option (which resulted in display<BR>
of a black block in 3.2), I now get an error message that says "Cannot<BR>
volume render since no point (or cell) data available."<BR>
<BR>
Has the volume-rendering-of-image-data feature been excised from version<BR>
3.8?<BR>
