Toggles

There are 2 main ways to create toggles in Unity, Direct Blend Tree and Layers. Both have their strengths and weaknesses.

Direct Blend Trees are generally considered more performant than Layers for lots of simpler toggles. While Layers can have much more complex logic, at the cost of performance when having a lot of them.

Be sure you have seperate On and Off animations before you begin with Direct Blend Tree and Layers. If not look at Creating Toggle Animation
