A resource to add to an [AnimationNodeBlendTree]. Blends two animations out of three additively out of three based on the amount value. This animation node has three inputs: - The base animation to add to - A "-add" animation to blend with when the blend amount is negative - A "+add" animation to blend with when the blend amount is positive If the absolute value of the amount is greater than [code]1.0[/code], the animation connected to "in" port is blended with the amplified animation connected to "-add"/"+add" port.
