  File "/home/noel/shocks/yt-x86_64/src/yt-hg/yt/visualization/volume_rendering/camera.py", line 611, in finalize_image
    if self.transfer_function.grey_opacity is False:
AttributeError: 'MultiVariateTransferFunction' object has no attribute 'grey_opacity'

It seems the MultiVariate (as well as Planck, see issue #605) transfer function was not updated after opaque volume rendering was added.
