When using generic rig, to reuse different animation clips for different characters, the character rig and the animation rigs structure must be the same.
When using 2D Freeform Blending with generic rig, locomotion animations (Walk/Run/Dash) need to have synced legs animation (eg, movements start with left leg). [Animator Setup : Movement Layer](Animation Blend Weight Selection By Animation Clip 5dd250479f104d0a98930d1bceda0146.md)
Animation Transitions need to be set at certain value (eg 0.3s). This means that every animation’s length need to be at least 0.3s.

Some animation clip can use fullbody blending and some can use upper-lower body blending. Example : Sword attack animation should use full body animation, but ranged attack can use upper-lower body blending when shooting/aiming while moving. To control which blending will be used, we can use animationEvent. But this means that we need to make sure that the transition into the clip includes the animationEvent (eg, if animationEvent is at 0s, then the transition needs to start at most at 0s) Details : [Animation Blend Weight Selection By Animation Clip](Animation Blend Weight Selection By Animation Clip 5dd250479f104d0a98930d1bceda0146.md)

Unity doesn’t provide State Machine Behavior OnStateChange to detect when is an Animator State is changing, there are some approach to detect when is Animator State is changing, using OnStateUpdate by detecting animation clip change everyframe, or using other AnimatorState’s OnStateEnter Details : [Detecting Animation State Change in StateMachineBehavior](Detecting Animation State Change in StateMachineBe 68604e4ad1a34952bc54e7e5b3262f4f.md)
Some approaches in preventing/cancelling animation events when the animation state is in transition, each has their own pros and cons :

If there are multiple listener with the same name but different parameter, Unity Animation Event will trigger only one corresponding function, starting from function with int parameter, float parameter, string, and lastly object ref parameter. The function can also receive AnimationEvent parameter
