Hi Sam,
Embree/pyembree are only useful for unstructured mesh data, *not*
hexahedral mesh data. I don't think support for volume rendering hexahedral
mesh data has been added to yt.

Dear yt-users,
I have had generally a very smooth ride in the past using yt for volume rendering of data on a uniform Cartesian grid. Now, however, I am trying to do similar things with data on a non-uniform Cartesian grid, having loaded it in with load_hexahedral_mesh.
I managed to get embree, pyembree built together with yt version 3.3-dev. I can create the hexahedral dataset with no problem (at least no errors), but when I try to create a scene in which to do some volume rendering I get the error copied below. I think I must doing something wrong but I don't know what!
Thanks and Best Wishes, Sam
