Interactor designed to create interactions (in seconds) that involves body movements with or without any animation files. Handles its own IK but also has one-click switch for Final IK integration.
Interactor designed to cover all aspects of any kind of interaction, from the designing stage in the editor to handling complex interactions in runtime. It contains editor tools to simplify process of preparing a fully interactable environment (Look at Easy Workflow section below). And in runtime, it handles which player parts are going to interact with which parts of the interacted object, while using its own IK to animate player bones.
