AnimTree Node
The AnimTree node is the root of the AnimTree. Initially, it has two inputs: Animation and Morph. These allow you to create networks to control the skeletal animation and morph targets applied to the mesh the AnimTree is assigned to. The AnimTree node can also have additional inputs added to allow the use of skeletal controllers to control the bones in the skeletal mesh. This can be accomplished by right-clicking on the AnimTree node and choosing Add SkelControl Chain. From there, a dialog will appear allowing you to choose the bone to control. Once a bone is chosen, a new input will appear on the AnimTree node with the name of the bone. The Animation input will have a network consisting of various Animation and Animation Sequence nodes connected to it. The Morph input will have a network consisting of various Morph nodes connected to it. The various SkelControl bone inputs will have networks consisting of various Skeletal Control nodes connected to them. Each of these types of inputs and nodes are color-coded so you can quickly decipher what type you are dealing with. The Animation input and Animation nodes are orange, while the Animation Sequence nodes are a dark red. The Morph input and nodes are purple. The SkelControl inputs and Skeletal Control nodes are green. AnimTree Properties:- AnimGroups - List of animation groups used to synchronize animations.
