A resource to add to an :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`. Blends two animations together additively out of three based on a value in the ``[-1.0, 1.0]`` range.

This node has three inputs:

- The base animation to add to

- A -add animation to blend with when the blend amount is in the ``[-1.0, 0.0]`` range.

- A +add animation to blend with when the blend amount is in the ``[0.0, 1.0]`` range
