Combining Deformation Chains and Free Deformation Points

The Weighted Deform node can act as a composite for several deformation methods. You can combine one or several curve deformations, with each curve deforming their area of the drawing. You can combine a curve deformation with free deformation point, where each point deforms their area of the drawing, and the curve deformation acts like one long curvilinear free deformation point. You can also combine an envelope deformation with free deformation point. This creates a zone, and free deformation points will only deform areas of the drawings on their side of the envelope.

For example, if you create an envelope inside a drawing, then add free deformation points outside of the envelope, the free deformation points will deform the drawing outside of the envelope only.

Free deformation points are created by connecting pegs to the Weighted Deform node, and defining their pivot point as their resting position. To combine free deformation points with a deformation chain, or several deformation chains together, all you need to do is connect them all to the same Weighted Deform node. The Weighted Deform node is a lot like Composite node for deformations. It will have as many input ports as there are nodes connected to it.

The steps below explain how to reproduce this specific deformation rig, which will result in the example further above. They can be adapted to combine any kind of deformations in a Weighted Deform node.
