Blends two of three animations linearly inside of an [AnimationNodeBlendTree]. A resource to add to an [AnimationNodeBlendTree]. Blends two animations out of three linearly out of three based on the amount value. This animation node has three inputs: - The base animation to blend with - A "-blend" animation to blend with when the blend amount is negative value - A "+blend" animation to blend with when the blend amount is positive value In general, the blend value should be in the [code][-1.0, 1.0][/code] range. Values outside of this range can blend amplified animations, however, [AnimationNodeAdd3] works better for this purpose. $DOCS_URL/tutorials/animation/animation_tree.html
