[yt-users] parallel volume render returns blank image

[Britton Smith]

Hi,

I'm doing a pretty simple volume render that uses the Camera.snapshot
function.  In serial, everything seems to be working fine, but when I run
in parallel, the image comes out completely blank.  I have gone into the
snapshot routine and verified that the image array is all zeros for every
processor after the loop:
for brick in self.volume.traverse(self.back_center, self.front_center,
image):

This is in the tip of the development version of yt.

Does anyone know what the issue is here?

Thanks,
Britton
