Volume render with two variables?
Hi everyone, Is there a simple way to do a volume rendering of two variables simultaneously? For example, if I wanted to overplot both density and temperature into a single volume rendering. My naive method would be to define a new variable which is a weighted sum of the two variables, and sculpt the transfer function to have different colors over the range. I'm just asking if there's a better way built into YT. I've done a lot of searching through the documentation, but I can't find a clear answer as to whether this is a built-in feature. I've seen examples from a few years ago where both variables are rendered separately, and the PNG files are combined. This ends up with both variables being partially-transparent to the other variable; in my example, I'd prefer *not *to see through a particularly high-temperature region. I've also seen documentation on a "multi-variate transfer function", but that documentation is pretty incomplete. Thanks in advance!
