Unity-AnimatorTransitionCopier

AnimatorTransitionCopier is a simple tool for copying and pasting animation transitions in the Animator editor.

It can help alleviate the frustration of having to manually redo all the animation states in a large state machine when making changes, such as switching from a clip to a blend tree.

FAQ

Can it copy transitions between state machine and state??

YES

We solved this issue on #3, #4.

Pasting AnyState and EntryState seems broken?

NO, IT WORKS

It's kind of a Unity bug that the editor doesn't refresh immediately when you paste the transitions of entry or any state in non-first state machine.

But it actually works, just a UI bug.

Environment
