Animation Parameters
Overview
Each Anim Tree instance can hold a set of parameters that can be modified externally and read internally of the nodes.
Creating Parameters
Click 
to select a needed parameter type to add a new parameter.
Searching Parameters
In the Animation Parameter window, select Name in the drop-down box, then you can enter the name in the Search Bar next to it to find the corresponding parameter.
Select different parameter types in the drop-down box and all parameters of that type will be filtered below.
Deleting Parameters
Select the parameter to be deleted, right-click to open the shortcut menu and select Delete Parameter.
Editing Parameters
In the new Parameter entry, Parameter Name, Parameter Preset Value and Parameter Instance Value can be edited.
The Parameter Preset Value refers to the default value of the Anim Tree.
The Parameter Instance Value refers to the parameter value in the current Anim Tree instance. Modifying this value can affect the Anim Tree in real-time.
Using Parameters
For example, in the Blend Pose By Int node, the control values of node can be specified by using parameters, so that the animation data processing inside the Anim Tree can be controlled externally.
Another example is that in the Blend Pose By Boolean node, various parameters can be applied for conditional expressions, and the final results are used to control the blend of nodes.
