Splitting volumes after pyro sim

Recommended Posts

Hi, I am creating a scene that is on fire where at one point an explosion happens. I did this by creating a different source for the explosion, giving it more divergence, temperature,....

However since they are merged and both sourced into the same pyro solver (at SOP level, Houdini 18), this is difficult for shading. Since the explosion is way hotter, the temperature scale etc... needs to be different for the explosion.
I have thought of just simulating them both seperately but they influence each other so that is not really an option and since it is pretty HQ, it will probably take way longer too.

The same basic question has been asked and answered as well: 

 but I have fire and heat and burn and flame fields, so just copying the density fields to different custom fields doesn't work, at least when I tried,... Also the solver is on SOP level in my case because it's easier and that also changes stuff I thin.

If you could help me with this I would be eternally grateful!

Thanks in advance,
Thoran Slock
