[SOLVED]smoke color using Cd volume (karma pyro)

[Kaito Ishikawa]

Hello!
I have a question about the Pyro shader using Karma in Solaris.

I want to use the Cd volume created in SOP for smoke color, but I don't know how.
Redshift has a tutorial, but I want to use Karma CPU.

I also want to use Cd volume for smoke color in karma, like in this tutorial. However, since I'm creating an explosion this time, I want to use scatter and control the flames as well.
So my ideal setup would be to use the karma pyro shader as a base, set Cd volume to smoke color, and keep the scatter as-is.

As at the beginning of this tutorial, I created a CD volume.

Please tell me if you know!

Thank you,

Thank you, tamagochy!
I've already known the parameter, but it didn't work.

Problem Solved!
The problem was that splitting the explosion simulation into three parts and using vdb merge caused Solaris to recognize three volumes, with the Cd only present on one of them.
Using vdb combine instead of vdb merge allowed me to recognize the volumes as a single unit.
And "Tint Smoke Color with Cd" is worked.

Thank you, tamagochy!
