What is Blend parameter in Unity Animator?

Question

When I do some changes to my animators, sometimes I notice a float parameter named Blend with value of 0.0 appears in the parameter list of the animator.

I think this happens when I change blending mode or weight of a layer.

I didn't find any documentation for this. Anyone knows what does this parameter do and how to use it, Is it safe to delete it?

Answer 1

Blend is a default float variable they included for you to use in your scripts. You can safely remove it if you wish. The method for controlling animator variables is Anim.SetFloat . For example you might want to replace it with 'movementDirection' on a character controller. In Mechanim you control blends between x and y axis of animation combinations using external variables such as Blend
