After you create the flare deformer, its handle is displayed in your scene and its nodes are listed in the Channel Box. The nodes include the flare handle node (default name: flarenHandle), the flare handle shape node (flarenHandleShape), and the flare deformer node (default name: flaren).
You can edit the effects of the flare deformer by editing the flare handle node and the flare deformer node. You can move (translate), rotate, and scale the flare handle to edit the effects of the deformation. You can also edit the flare deformer node’s keyable attributes (channels), which are displayed in the Channel Box.
You can edit flare deformation effects in the following ways:
To edit with the flare handle manipulators
The manipulators on the flare deformer handle let you to edit attributes interactively.
To edit flare deformers by moving, rotating, or scaling the handle
To edit flares with the Channel Box
One quick way to select the flare deformer node is to select the object being deformed, and then select the flare deformer node in its history from the Channel Box (under INPUTS).
You can control which attributes are listed as keyable attributes (channels) in the Channel Box with the Channel Control editor (select Window > General Editors > Channel Control).
To edit flare deformers with the Attribute Editor
See flare.
The flare deformer handle, flare deformer handle shape, and flare deformer nodes are all deleted. However, the object still has the tweak node as an input node, so any tweaks you might have made are preserved. Also, note that the various input nodes that structure the evaluation of the deformation are not deleted.
