[yt-users] Volume rendering issues

[Matthew Turk]

Hi Mike,

I think this *might* be related to some bugs I fixed in the volume
rendering in the mercurial repo.  You can hot swap the two out:

cd /home/butler85/yt/src/
hg clone -r stable http://hg.enzotools.org/yt/ yt-hg
rm -rf yt-1.7-svn
cd yt-hg
python2.6 setup.py develop

Feel free to remove the "-r stable" if you want to use 2.0, but be
forewarned that the API has changed slightly.  :)

If it's still not working, let me know, I'll crank down on it.

-Matt
