Hi all I'm not having any success with off-axis projections using the pf.h.camera() with AMRKDTree and ProjectionTransferFunction(). cam.snapshot() returns an all-zeros array, even in situations where ColorTransferFunction() produces great images. This script (based on the first part of amrkdtree_downsampling.py) demonstrates the problem: http://paste.yt-project.org/show/3072/ Any ideas what's going wrong? Maybe something to do with preventing the log'ing of the field, which I attempted to do with "pf.field_info['Density'].take_log=False"? Thanks for you help!
