In this tutorial we show you how to set up Space Switching ie. a Dynamic Parenting constraint in akeytsu. This will be illustrated for a classic juggling act making use of the akeytsu toolset.
Space Switching also called Dynamic Parenting in other software packages lets you link a joint to another so that they behave as if they had a parent-child relationship. In other words the object that is space switched becomes related to the object that is defined as Space Origin. Move, Rotate and Scale transforms of the targeted objects (Joint, IK, RF...) are inherited from MRS values of the assigned Space or Dynamic Parent object.
Contrary to hierarchy structure, this constraint is dynamic and can evolve in time by keying new Spaces on a dedicated layer. This is a precious tool when animating a character interacting with props.

Beta notice : Space switching is flagged as Beta for now. We delivered something permissive and flexible that can be easily used but we anticipate workflow and UI improvements early 2021 to improve user experience.
QUICK START INSTRUCTIONS
Each Space Switching key needs to be added over at least one corresponding MRS key including the targeted object. In the below example the Healing Potion is the target object and we have extracted ait into a specific layer. We then create a new Space Switching layer with Potion_Healing selected in the Picker and choose right wrist as new Space ie. Dynamic Parent.
