[Paraview] Selecting volume rendering causes output to vanish

[Burlen Loring]

Hmm. If Bunyk ray cast doesn't work some thing strange is going on as 
that is a software(non gpu) algorithm and should always work.

Can you get anything to show up using a small test data? For example 
create a wavelet source and apply a threshold (use default values) to 
convert to unstructured data. If that works maybe something with your 
input data, or size of it.
