blend

Go to: Related nodes. Attributes.

        This node blends one or more numeric inputs.
        Note that this node is a virtual class, and so the blending function
        is defined by the derived blend classes.

        The common thing for all blend nodes is that there is a current driver.
        The current driver attribute is a scalar number specifying which of the
        multi-input attributes is the current driver. The current driver input
        is used by several commands to specify which of the multi-input attributes
        to operate on. For example, the setDrivenKeyframe command will set a
        keyframe on the input with the multi-index specified by the current driver.
