Subject: Rendering large datasets using offscreen rendering...

Folks, I need some tips for rendering a large dataset using offscreen 
rendering in a SGI Altix-ICE.

Basically, I have a 40 million tetrahedra mesh partitioned in 128 cpus. 
The result is stored in Xdmf format (15 time steps) and I can 
successfully load the datasets in ParaView 3.4.0 and do basic things  
like plot the result in isosurfaces or colorize the model with a scalar 
field. The problem begins to happen when I try to change the model 
opacity. PV takes forever before crashing MPI.

I guess that the problem with opacity is due to the compositing order 
but I can't figure out a way to use it. I already tried to disable 
ordered compositing but it hasn't helped so much.

Any idea would be appreciated. Thanks,

Renato.
