[yt-users] Strange artifacts in volume rendering movie made using parallel_objects

[Sam Skillman]

Hi Nathan,

This is pretty weird -- Can you print out cam.comm.rank and cam.comm.size
just after you create the camera object?  The only thing I can think of is
that there is some invalid reference to the wrong communicator.  When doing
this you can get rid of the cam.snapshot so that it runs through the code
much faster.  I'll be on IRC tomorrow morning as well if you want to catch
me there.
