Volume Info Node¶
![Volume Info Node.](../../../_images/node-types_ShaderNodeVolumeInfo.webp)
The Volume Info node provides information about Smoke Domains.
Inputs¶
This node has no inputs.
Eigenschaften¶
This node has no properties.
Outputs¶
- Color
Gives the color of the smoke inside the Fluid Domain. The color and vector outputs are the same. The Factor output is an average of the channels.
- Density
Gives a scalar defining the density of any smoke inside the Fluid Domain.
- Flame
Gives a scalar defining the density of any fire inside the Fluid Domain. All three outputs are the same.
- Temperature
Gives a scalar defining the temperature of the volume. Values in the range 0 - 1 map to 0 - 1000 kelvin. This may be used to render physically-based fire with the Blackbody or Principled Volume shaders. All three outputs are the same.

Computing the color of fire using the Blackbody node. Since the Blackbody node expects its input in Kelvin, the temperature output has to be remapped first.¶
