Transfer Attribute Node

The Transfer Attribute node retrieves values from a source geometry and provides them as a field, so they can be used anywhere.

Inputs

Source

The geometry to retrieve the attribute from.

Muista

This node only supports instances in the source geometry when the Mapping method is set to Index.

Attribute

A field to evaluate on the Source geometry for use with the transfer method.

Source Position

The position to start from when finding the closest location on the source mesh or point cloud. Used in the Nearest Face Interpolated and Nearest modes. By default, this is the same as if the Position Node was connected.

Index

Which index to use when retrieving the data from the input field in Index mode. By default, the index is used, meaning that the data from the source attribute is copied directly to the output. However, a different index can be connected, resulting in a ”shuffling” of the values. Indices that are either too large or below 0 are clamped.

Vihje

To retrieve a single attribute value instead of a field, a single integer input or the Integer Node can be connected to this socket.

Properties

Domain

The attribute domain that the attribute is transferred from, or in other words, the domain used to evaluate the Attribute input. For example, it is possible to transfer data from the faces of one geometry to the points of another.

Mapping

How elements from the destination geometry are mapped to the output.

Index

Copy the attribute data from the value at the input index. In this mode, the source geometry can consist of a mesh, point cloud, or curve. The matching component type from the context will be chosen if possible, otherwise a component will be chosen in that order.

Nearest Face Interpolated

Transfer the attribute from the nearest point from anywhere on the surface. Non-face attributes are interpolated across the surface (edge attributes are not supported yet). Loose points and edges are ignored.

Nearest

Transfer the attribute from the nearest element (with a domain chosen by the Domain input). No interpolation is done.

Outputs

Attribute

The data retrieved from the Source geometry, mapped based on the node’s settings and inputs.

Examples

Transferring the position of vertices from a different object’s geometry, assuming that they have the same number of points.
