[Paraview] Python tracing doesn't work for opacity time frames?

[Robert Sawko]

Hi,

I am trying to script paraview to ramp up opacity of some objects, but it seems
that the tracing functionality isn't working. I've selected maximum verbosity
options in Tools->Start trace, but nothing is produced.

Could anyone perhaps share a script with Opacity? I've been able to work
out camera actions with PV, but it seems to me that opacity ramping is more
difficult as it needs some reference to an object it's meant to affect.

Please let me know,
Robert
