New issue 381: cam.snapshot() not working right in parallel
https://bitbucket.org/yt_analysis/yt/issue/381/camsnapshot-not-working-right-in-parallel

Astrodude87:

Hello,
I have a script that works in serial to make a volume render with the cam.snapshot() tool, but in parallel the image is missing some regions, or is just black in some cases. The script is attached to run with the Enzo_64 dataset from the workshop, but changing the comments makes it work for my own data (Bullet). Attached are also the results from running it in serial vs in parallel for the Enzo case and my own case.

mpirun -np 4 pyyt make_vol_rend2.py --parallel (and I have mpi4py installed),

Output is expected, and no errors are announced. Seems to run fine, just the image isn't coming out as expected.

Cheers,
  -Mark
