Attribute Node

Attribute Node.

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

輸入

This node has no inputs.

屬性

Name

Name of the attribute.

Type

Specifies the type of the attribute.

Geometry

The attribute is associated with the geometry of the object, and its value varies from vertex to vertex, or within the volume of the object.

Most geometry attributes are directly accessible through the various input nodes, except for these:

Vertex Color Layers

These can be retrieved this by their names.

Ocean Foam

Gives a scalar defining where foam might appear when using an Ocean Modifier. This depends on the name you give this property.

Object

The attribute name specifies a custom property name, or an RNA path to a built-in property (like the single property driver variables).

The values of attributes of this type are defined once per object. The name or path is looked up first in the object data-block, followed by the mesh data-block if not found. Custom properties have priority over built-in ones.

The property value must be an integer, float, or a vector of 1 to 4 floats; properties of other types are ignored. If a suitable property is not found, all sockets of the node, including Alpha, output 0.

Tip

The color attribute will output the value of the Color field in the Viewport Display panel of the object, unless overridden by a custom property.

Instancer

Similar to Object, but the attribute is looked up in the instancer particle system settings, followed by the instancer object. If the current object is not instanced, or the property is not found, it falls back to the Object mode.

輸出

色彩

RGB color interpolated from the attribute.

Vector

XYZ vector interpolated from the attribute.

Factor

Scalar value interpolated from the attribute.

Alpha

Alpha channel of the attribute, when available. If the attribute has no alpha channel, generally defaults to 1.

Note

Currently, attributes are not supported in shaders used for the World or Light Objects.
