I've updated the 3.0 toggle loco controller again, the updated version is here:

This controller allows you to switch between locomotion animations and "floating" for FBT using the expressions menu. Note that this version requires the newest SDK. 

If you're upgrading from a previous version you need to change the type of the "WalkDisabled" param to bool. Do this for the param file of each avatar using this new controller. Changes include instantly toggling your loco while moving, and switching to a bool parameter to save parameter bits. 

If you haven't used a previous version of the controller, to set it up you need to:
- Drag and drop this controller into the "Base" layer in your 3.0 avatar controller
- DISABLE "Force locomotion animations for 6 point tracking" in your avatar controller!
- Add a parameter called "WalkDisabled" (case sensitive) to your param file with type Bool
- Set up a toggle on your avatar menu for that parameter
