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.
The geometry to retrieve the attribute from.
This node only supports instances in the source geometry when the Mapping method is set to Index.
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.
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.
To retrieve a single attribute value instead of a field, a single integer input or the Integer Node can be connected to this socket.
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.
How elements from the destination geometry are mapped to the output.
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.
Transfer the attribute from the nearest element (with a domain chosen by the Domain input). No interpolation is done.
The data retrieved from the Source geometry, mapped based on the node’s settings and inputs.
