Attribute Node.

The Attribute node allows you to retrieve attributes attached to an object or mesh.

Inputs

This node has no inputs.

Properties

Name

Name of the attribute. Most attributes are more easily available through the various input nodes, except for these:

Vertex Color Layers

These can be retrieved this by their names.

Density

Gives a scalar defining the density of any smoke inside the Smoke Domain.

Color

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.

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.

Flame

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.
