I created a fluid source and am bringing that into my simulation as a volume source but it is no longer showing the heat attribute that existed in the cached fluid source before.

How do I gain access to it in my pyro, I want the heat to use to drive emission in the Redshift Volume material, because the temperature voxel resolution is really low in renders when I try it that way. I have been working around it by setting the density field to heat in Sop To Dop bindings but this only works sometimes and is buggy and unpredictable for some reason.

Thanks
