Hello,
I have a 2 volume data(Gas_Density.df3 and Gas_Temperature.df3) on a grid
512^3 in df3 format.
The data from cosmological simulation.
How can I combine this 2 medias in such a way, where
emission/absorption/intensity will calculated from Gas_Density.df3 and for
color coding will use Gas_Temperature.df3?
I used simple way only to show one media and its looks like:

Following script whas used to render it:
#declare box_map=color_map{
[0.0 rgbt <0,0,0,0>]
[0.090000 rgbt <0,0,0,0>]
