Solo and Mute functionality

In complex state machinesThe set of states in an Animator Controller that a character or animated GameObject can be in, along with a set of transitions between those states and a variable to remember the current state. The states available will depend on the type of gameplay, but typical states include things like idling, walking, running and jumping. More info

, it is useful to preview the operation of some parts of the machine separately. For this, you can use the Mute / Solo functionality. Muting means a transition will be disabled. Soloed transtions are enabled and with respect to other transitions originating from the same state. You can set up mute and solo states either from the Transition Inspector, or the State Inspector (recommended), where you’ll have an overview of all the transitions from that state.

Soloed transitions will be shown in green, while muted transitions in red, like this:

In the example above, if you are in State 0, only transitions to State A and State B will be available.

  • The basic rule of thumb is that if one Solo is ticked, the rest of the transitions from that state will be muted.
  • If both Solo and Mute are ticked, then Mute takes precedence.

Known issues:

  • The controller graph currently doesn’t always reflect the internal mute states of the engine.
