[Paraview] [EXTERNAL] Fwd: Volume rendering with RGBA data

[Scott, W Alan]

Ruq,
Volume rendering vectors appears to have multiple bugs.  And you are correct – volume rendering a non map scalar vector appears to turn on map scalars.

I wrote up bugs.

Subject: [EXTERNAL] [Paraview] Fwd: Volume rendering with RGBA data

Hello,

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.
