Procedural modeling involves editing a variety of parameters and their variances that govern the creation of a tree. Generators are the objects that provide this level of procedural generation.

Generators create and control groups of Nodes, which comprise the geometry of tree model. Editing the values and variances of the Properties of the Generators and controlling their hierarchy creates the procedural generation of the tree.

The Generator Editor is where you edit the basic structure of the tree. Generators are connected here, and the tree's procedural structure can be edited by changing these connections.

There are several types of generators that create different types of geometry in the tree.

Decorators are a way of spawning exterior parts to give a tree interesting and unique features.

	Cap Generator The Cap Generator closes off open-ended branches.
	Knot Generator The Knot Generator creates an extra piece of geometry attached to a branch, such as a knot, lump, or cavity.
	Fin Generator Fin Generators create a thin flap of geometry that can be used for fungus, moss, or other things that hang off a trunk or branch.
	Shell generator A Shell is a special kind of Branch that sits on top of the parent branch, allowing you to wrap the parent in moss, algae, or low-poly vines.
