THE ATTRIBUTE TRANSFER NODE
This tutorial looks at the practical applications of the Attribute Transfer Node which passes information from one object to another based on their position in space.
It starts with a refresher on Houdini attributes, then demonstrates a simple attribute transfer and explains the parameters settings of the node.
The bulk of the tutorial is the creation of a network that creates tree roots spreading across a hillside. It uses Attribute Transfer in many different ways to pull all the elements of the scene together so that the tree roots or the shape of the ground underneath can be changed and the rest of the scene procedurally adjusts to it.
