Houdini 22.0 Nodes Copernicus nodes

Attribute Copernicus node

Creates a detached attribute.

On this page
Since 22.0

This node creates a detached attribute. The node creates the attribute either with a specific size or based on an input attribute (attrib_ref).

Use this node to reserve arbitrary array sizes or get a matching attribute of a different type to an existing attribute.

Parameters

Signature

The attribute type to generate. This doesn’t have to match the input.

See Signatures for more information.

Class

Detached attributes have a property that hints at what class to consider the attribute as, and this sets that class.

Input

Use the class from the input attrib_ref.

None

Prevent automatic deduction on insertion.

Detail

Use a detail attribute.

Primitive

Use a primitive attribute.

Point

Use a point attribute.

Vertex

Use a vertex attribute.

Value

The value to initialize the float attribute to.

Value

The value to initialize the vector 2 attribute to.

Color

The color to initialize the vector attribute to.

Color

The color and alpha to initialize the vector 4 attribute to.

Value

The integer to initialize the integer attribute to.

Sizing Method

The method used to compute the attribute’s size. When an attrib_ref is connected, the base size is the input’s size. When there’s no input, the base size is 0.

Set

Use the Size parameter and ignore any input size.

Add

Add the input size and Size parameter values.

Multiply

Multiply the input size with the Multiply Size parameter value.

Size

The size of the attribute to Set or Add.

Multiply Size

The scale amount by which to resize the attribute.

Type Info

The property that hints at how to interpret the attribute.

None

No special treatment.

Position

This attribute is a geometric point. Houdini transforms the attribute as a position.

Vector

Houdini transforms the attribute as a vector.

Normal

Houdini transforms the attribute as a normal.

Color

This attribute is a color.

Quaternion

Houdini transforms the attribute as a quaternion.

Transform Matrix

Houdini transforms the attribute as a transformation matrix.

Texture Coordinate

This attribute represents texture coordinates, like uv.

Inputs

attrib_ref

An optional reference attribute on which to base sizing and initial properties.

Outputs

attrib

The newly created attribute of the given type and size.
