I'm trying to make a volume rendering of one of my binary Gadget dataset. I'm following this tutorial: http://yt-project.org/docs/dev-3.0/cookbook/simple_volume_rendering.py, which has been working great for my Enzo outputs. But the same script is not working with the Gadget ones. The error I'm getting is "Failed to split grids" when I try to do "cam = pf.h.cam()". I checked if yt is reading the Gadget file in the right way by plotting the particles, and it looks good. Any ideas of what can be causing that problem?
