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

[Nathan Goldbaum]

Hi all,

I'm running into some weird issues when I try to make a time series volume rendering movie using parallel_objects.   

The script I'm running is pasted here: http://paste.yt-project.org/show/2206/

And the resulting movie is located here: http://ucolick.org/~goldbaum/files/volume.avi

The movie is stitched together using ffmpeg but i've confirmed that the artifacts are present in the individual frames.  This is not due to my use of the enhance script since the artifacts appear in the raw frames and in fact the movie was stitched together using the raw frames.  I don't see any artifacts when I volume render individual frames in serial.  I'm doing one processor per file parallelism.

Thanks for your help with this - I know there's a cool looking movie buried in there somewhere.
