flow

Go to: Related nodes. Attributes.

This is the flow node which is an interfacing node among a motionPath node and lattice deformation related nodes.

The flow node communicates with the motionPath node through messages to compute and construct a set of lattice points (used by the lattice node, and the ffd node) to deform the geometry objects connected to them.

When the latticeOnObject attribute is set to true, the lattice points are positioned around the animated object. Otherwise, they are positioned around the path curve.
