- Vertex Color Layers
These can be retrieved this by their names.
Gives a scalar defining the density of any smoke inside the Smoke Domain.
Gives the color of the smoke inside the Smoke Domain. The color and vector outputs are the same. The Factor output is an average of the channels.
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.
Gives a scalar defining the density of any fire inside the Smoke Domain. All three outputs are the same.
- Ocean Foam
Gives a scalar defining where foam might appear when using an Ocean Modifier. This depends on the name you give this property.
